Interface properties of Si-SiO2-Ta2O5 structure by cathodoluminescence spectroscopy
Publisher: AIP Publishing
Date: 05-02-2016
DOI: 10.1063/1.4941270
Abstract: We studied formation of the SiO2-T2O5 interface in the Si-SiO2-Ta2O5 structure using Cathodoluminescence Spectroscopy (CLS). Analyzing the evolution of CLS spectrum of the Si-SiO2 structure while depositing the Ta2O5 layer allowed to estimate an optical transmittance of the Ta2O5 layer and its band gap. Spectral features related to the formation of the SiO2-Ta2O5 interface were identified by comparison of the experimental CL spectrum of the Si-SiO2-Ta2O5 structure and its simulated counterpart. This formation involves a decomposition of silanol groups at the outer surface of the SO2 layer and creation of the SixTayO-type layer containing luminescence centers with the emission band centered at 3 eV photon energy.

Highly efficient time-of-flight spectrometer for studying low-energy secondary emission from dielectrics: Secondary-electron emission from LiF film
Publisher: AIP Publishing
Date: 03-2003
DOI: 10.1063/1.1537044
Abstract: A highly efficient time-of-flight electron spectrometer is described. An incident electron current of the order of 10−14 A makes it suitable for studying secondary emission from dielectric surfaces. A microchannel plate position-sensitive detector allows flight distance correction while keeping a large acceptance angle. Measured energy distribution curves of secondary electrons generated from a LiF film by 19–31 eV incident electrons demonstrate good energy resolution and reveal reproducible and stable emission features at 2.6±0.3 eV, 7.2±0.3 eV, and 10.3±0.3 eV.

Abstract: Data have been obtained for ejection of valence shell 4p and 3d electrons in krypton and the 1 t 2 and 2 a 1 orbitals in methane. Measurements, with kinematics both on and off the Bethe ridge, examine how the spectral shapes change for fixed energies of 1015 eV for the incident electron, 880 eV for scattered and 120 eV for ejected electron and angular momentum changes. The studied interactions are activated by excitation and ionization of inner shell (-d) electrons and concern complex electron correlations. The triple differential cross sections for the Bethe ridge conditions within the experimental accuracy are similar to the values predicted by the Distorted Wave Impulse Approximation and Born Approximation calculations but need further consideration of electron correlation effects.

Abstract: We performed low-noise broadband microstrip ferromagnetic resonance (FMR) measurements of the resonant modes of an array of metallic ferromagnetic nanostripes. In addition to a strong signal of the fundamental mode, we observed up to five weak- litude peaks in the field-resolved FMR traces, depending on the frequency. These higher-order absorption peaks have been theoretically identified as due to resonant excitation of odd and even standing spin waves across the direction of confinement in array plane (i.e., across the stripe width). The theory we developed suggests that the odd modes become excited in the spatially uniform microwave field of the FMR setup due to the large conductivity of metals. This promotes excitation of large- litude eddy currents in the s le by the incident microwave magnetic field and ultimately results in excitation of these modes. Following this theory, we found that the eddy current contribution is present only for patterned materials and when the microwave magnetic field is incident on one surface of s le surface, as it is in the case of a microstrip FMR.

Abstract: A relaxor electroceramic [Formula: see text]–[Formula: see text]–0.30-[Formula: see text] (PMN–PLT–BLT) with [Formula: see text] = 0.25, 0.50 and 0.75 was synthesized using the two combination methods of auto-combination and hot-pressing. Characterization of the crystal phase, microstructure, optical and dielectric properties of PMN–PLT–BLT was made primarily by X-ray diffraction and TEM and SEM methods. The pure perovskite crystals (rhombohedral and tetragonal) prepared at [Formula: see text] for 2 h calcination were revealed by using X-ray diffraction. The average optical transmittance of these electroceramics in the range between 450 nm and 900 nm is higher than 60% while in the IR region reached 100%. The PMN–PLT–BLT with [Formula: see text] = 0.75 displays the highest transparency around 70% near 1100 nm. The microstructures and dielectric measurements show that these three electroceramics have densities of about 98.8% and exhibit a normal relaxation characteristic.

Intensity asymmetry of the (00) diffracted spin-polarized electron beam scattered from W(110): Azimuthal dependence
Publisher: AIP Publishing
Date: 24-06-2013
DOI: 10.1063/1.4812751
Abstract: Intensity asymmetry of the elastically scattered spin-polarized electrons from W(110) surface at 22 eV primary energy and at 25° angles of incidence and detection ((00) diffraction beam) was measured as a function of the azimuthal angle. Experimental results are compared with the calculations based on the relativistic multiple scattering formalism. The comparison showed fairly good agreement. These support the general theoretical approach and the input data chosen for the calculations. The information gained from our work is important for the interpretation of results of various spin-polarized electron spectroscopies as well as for design and construction of multi-layered structures with spin-active interfaces.

Excitation of plasmons in Ag/Fe/W structure by spin-polarized electrons
Publisher: AIP Publishing
Date: 07-09-2015
DOI: 10.1063/1.4930841
Abstract: Using Spin-polarized Electron-Energy Loss Spectroscopy (SPEELS), the plasmon excitations were probed in a few atomic layers thick Ag film deposited on an Fe layer or on a single crystal of W(110). The measurements were performed at two specular geometries with either a 25° or 72° angle of incidence. On a clean Fe layer (10 atomic layers thick), Stoner excitation asymmetry was observed, as expected. Deposition of a silver film on top of the Fe layer dramatically changed the asymmetry of the SPEELS spectra. The spin-effect depends on the kinematics of the scattering: angles of incidence and detection. The spin-dependence of the plasmon excitations in the silver film on the W(110) surface and on the ferromagnetic Fe film is suggested to arise from the spin-active Ag/W or Ag/Fe interfaces.
Controlling spin–orbit interaction in a ferromagnetic Fe/Au double layer
Publisher: AIP Publishing
Date: 26-01-2015
DOI: 10.1063/1.4906932
Abstract: Using spin-polarized single- and two-electron spectroscopy, we probe exchange and spin–orbit interaction in a double layer of Fe and Au on W(110) and measure the spin asymmetry of the Bloch spectral density function of the s le. In a 5 ML iron film, the spin-orbit contribution to the measured asymmetry of the (e,2e) spectra was not detectable, whereas a deposition of about 1 ML of gold introduced a substantial spin-orbit component in the measured asymmetry. At the same time, this double layer still exhibits ferromagnetic properties: (i) the spectral density function asymmetry demonstrate imbalance of spin-up and spin-down electron densities in the valence band and (ii) the Stoner excitation asymmetry has almost the same value as in a pure Fe film.
Microwave magnetic dynamics in ferromagnetic metallic nanostructures lacking inversion symmetry
Publisher: AIP Publishing
Date: 14-03-2016
DOI: 10.1063/1.4942828
Abstract: In this work, we carried out systematic experimental and theoretical investigations of ferromagnetic resonance (FMR) responses of quasi-two-dimensional magnetic objects—macroscopically long stripes with nanoscale cross-section made of ferromagnetic metals. We were interested in the impact of the symmetries of this geometry on the FMR response. Three possible scenarios from which the inversion symmetry break originated were investigated, namely: (1) from the shape of the stripe cross-section, (2) from the double-layer structure of the stripes with exchange coupling between the layers, and (3) from the single-side incidence of the microwave magnetic field on the plane of the stripe array. The latter scenario is a characteristic of the stripline FMR configuration. It was found that the combined effect of the three symmetry breaks is much stronger than the impacts of each of these symmetry breaks separately.
Plasmon-assisted high reflectivity and strong magneto-optical Kerr effect in permalloy gratings
Publisher: AIP Publishing
Date: 25-03-2013
DOI: 10.1063/1.4798657
Abstract: We demonstrate experimentally a strong plasmon-assisted enhancement of the transverse magneto-optical Kerr effect in permalloy gratings. The enhanced transverse magneto-optical Kerr effect is accompanied by an increased grating reflectivity with the maximum of enhancement being correlated with plasmonic Fano resonances. This correlation was confirmed by an intuitive Fano model and also through full-vectorial optical simulations. Simultaneously high reflectivity and transverse magneto-optical Kerr effect as well as narrowest ferromagnetic resonance linewidth and vanishing anisotropy make permalloy nanostructures attractive for applications in spintronics and nano-optics such as, for ex le, all-optical excitation of propagating spin waves and spectral tuning of optical nanoantennas.

Abstract: The design and performance of a thin bakable in-line valve are described. The valve is designed for use in electron scattering experiments for efficient and minimal spatial separation of ultrahigh vacuum from a region containing metal vapors, base pressure of 8×10−8Torr, or atmosphere. The simple compact design permits experiments with metal vapors and spin polarized electrons to be conducted with high efficiency and over months, without loss of emission from GaAs crystal or need for frequent bakeout of ultrahigh vacuum chamber.
