Magnetoresistance of film materials based on iron and noble metals

Abstract

Thin films based on iron and noble metals were evaporated on glass and sitall substrates by method of layered or simultaneous condensation. The magnetoresistivity properties of films based on Fe and Pd, Cu or Au were studied and shows what character of the dependence and the amplitude of magnetoresistance are determined by the phase formation processes, namely by the processes of structural ordering in the films based on Fe, Pd and granulation in the films based on Fe and Au. Despite the relatively small amount of giant magnetoresistance, these film materials can be used as sensitive elements of strain sensors and magnetic fields, since the phase composition of the granules has wide temperature and concentration stability intervals.
