Ballistic magnetoresistance in thin film nanocontacts

Objective

The project explores a superior property in Nan scale magnetic thin film devices - the spin dependent ballistic electronic transport, which is a size-dependent phenomenon that may only occur in Nan scale materials and devices due to quantum mechanics effect. The subject area and the objectives of the project have a close relevance to the NMP priority area 3.4.1.1 for 2003, which calls for long term, ambitious interdisciplinary research addressing, theoretically (incl. modelling) and experimentally, size-dependent phenomena, including quantum and/or macroscopic scale phenomena. The Nan technology and Nan science explored in the project represent anew approach to materials science and engineering, as well as for design of new devices and processes for future data storage, spintronic devices and computers. The consortium consists of European leading experimentalists (P1) in BMR of wire Nan contacts, leading BMRtheorists (P5), laboratories with the state-of-the-art Nan fabrication techniques (P3) and magneto transport thin films and devices (P2 and P6), and leading researchers in spin injection and spin transport studies (P4), aiming to integrate the complementary knowledge, infrastructure and expertise for the exploration of the spin dependent ballistic transport properties in thin film Nan contacts. Our overall rare to employ the state-of-the-artnanofabrication technology for the fabrication of thin film vasoconstrictions with diameter of 50 ~ 5 nm, and to carry out a concerted experimental and theoretical study of the spin transport properties in relation to physical sizes, micro magnetic structures, interfacial and ferromagnetic/semiconductor electrode materials, and polarization in the vicinity of the Nan contacts, aiming to explore high ballisticmagnetoresistance (BMR), we will study the magneto elastic deformations of the contacts that can contribute to the transport process. As well as the contribution by pulsed laser illumination.
