Origin of ferromagnetism in zinc-oxide semiconductors: A vital element to spintronics. Zinc-oxide is a semiconductor which could potentially be applied for a new concept known as spintronics - a hybrid technology of electronics and magnetics.

Zinc-oxide is a semiconductor which could potentially be applied for a new concept known as spintronics - a hybrid technology of electronics and magnetics. The advantages of spintronic devices would be nonvolatility, increased data processing speed, decreased electric power consumption and increased integration densities compared with conventional semiconductor devices. A vital element to realizing this concept is a new class of semiconductor which exhibits magnetism. It has been reported that zinc-oxide doped with transition metal shows magnetization, however, its authenticity remains controversial. We will try resolving this problem by developing a fundamental understanding of the origin of ferromagnetism in zinc-oxide semiconductor.Read moreRead less

Soft magnetic materials are used as magnetic cores in electromagnetic devices such as transformers. The latest material development is the use of nanocrystalline soft magnetic alloys. Our theory and experiments have shown that the magnetic softness of nanocrystalline alloys is greatly influenced by directional atomic ordering, which increases magnetic anisotropy and consequently increases heat loss. We will employ a novel magnetic annealing technique to establish the relationship between this anisotropy and the soft magnetic properties of nanocrystalline alloys. Emphasis will be placed on eliminating the induced anisotropy in iron-cobalt based alloys and thereby produce ultra-efficient, magnetic core materials.Read moreRead less

Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.Read moreRead less
'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deli ....'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deliberate introduction of structural and electronic mismatches at an interface. Such purposely induced 'designer defects' in epitaxial oxide thin films will allow new properties to be achieved in nanoscale layers. This is expected to lead to a new class of functional materials to be used in sensors and nanoelectronics.Read moreRead less
