This project enables collaborations between Australian and European groups in an important and expanding area at the forefront of technology, and facilitates access to state of the art resources in laboratories in Austria and Spain. It carries across knowledge in synchrotron techniques just at the right time, just before the Australian synchrotron goes on line in 2008, allowing time to deepen expertise and to obtain specific knowledge. It will help establish a new effort at the University of Western Australia concentrated on developing advanced materials for technology. We will make important contributions to an internationally important area and offer high quality interdisciplinary research training in magnetic nanomaterials science.Read moreRead less
Time and frequency resolved magnetometry. Magnetism is well known as a source of fundamental unsolved problems in material physics and condensed matter. It is also an area famous for practical application: the ability to record and read information from magnetic materials is the basis of nearly all mass data storage devices.

Magnetism is well known as a source of fundamental unsolved problems in material physics and condensed matter. It is also an area famous for practical application: the ability to record and read information from magnetic materials is the basis of nearly all mass data storage devices. The aim of this project is to provide first measures of certain key energies and rates associated with magnetic processes. Through a combination of theoretical modelling and experiment design, a new experimental technique will be developed into a powerful analysis tool. This work will establish the technique in Australia and create new opportunities for future study.

Theoretical and experimental studies of exchange bias in thin films. Films containing layers of different types of magnetic materials - in particular, ferromagnetic and antiferromagnetic - have properties which are being exploited in magneto-electronic devices used in recording and manipulation of computer data.

Films containing layers of different types of magnetic materials - in particular, ferromagnetic and antiferromagnetic - have properties which are being exploited in magneto-electronic devices used in recording and manipulation of computer data. These properties are determined by new types of magnetisation processes in the interface between layers. In this project investigations of the magnetic behaviour of interfaces will be made to provide information of value in the design and optimisation of new and existing devices. The procedures to be developed in this project will be applicable to the understanding of the behaviour of a new range of atomically engineered magnetic structures.Read moreRead less

Spin-dependent interactions: a fundamental basis for spin-electronics. This project will establish a comprehensive understanding of spin-dependent interactions and correlated behaviour of multi-electron systems that are responsible for spin-relaxation, spin transport and spin coherence in spin-electronic devices.

This project will establish a comprehensive understanding of spin-dependent interactions and correlated behaviour of multi-electron systems that are responsible for spin-relaxation, spin transport and spin coherence in spin-electronic devices. Our approach is based on the spin-resolved two-electron coincidence spectroscopy that is inherently suited for studying electronic correlations. Systematic investigations of spin-dependent interactions in atoms, molecules and ultrathin films will increase understanding of magnetic (spin) properties of artificially structured materials with reduced dimensionality for the benefit of nanotechnology. This understanding will be used to design and control, at the quantum mechanical level, the building blocks of spin-electronic devices.Read moreRead less

The ability of infrared detectors to directly sense the thermal output of an object has applications in medicine, search and rescue, bushfire detection and in the defence and surveillance industries. The highest performing infrared detectors are photon detectors based molecular beam epitaxy (MBE) grown HgCdTe. The primary aims of this project relate to the fundamental understanding of p-type doping in MBE grown HgCdTe, a current and major difficulty in HgCdTe technology, and the use of such p-type MBE grown layers in conjunction with a newly developed plasma process based n-p junction formation technology to realise novel and innovative infrared detector structures. Such structures would have the ability to revolutionise the use of HgCdTe in infrared detectors and focal plane array applications.Read moreRead less
