Thermo- and magnetoresistive properties of the film systems based on Fe, Co and Pd

Abstract

The results of investigations of thermal and magnetoresistive properties of two-component film alloys based on Fe, Co, and Pd. It was found that in the process of film condensation Co/Pd and  Fe/Pd personality of the individual layers preserved hardly formed a disordered solid solution (s. s.) with fcc-lattice, which at the annealing proceeds in an orderly s. s. (L10 phase with tetragonal lattice) with elements of the granular state. The thermal coefficient of resistance has a relatively small value (on the order 10–4 К–1), which may indicate thermal stability of the alloy films. Magnetoresistance has all the signs of GMR, the value of which increases monotonically with increasing temperature annealing of films.
