抄録

Granular Fe₅₀Pt₅₀-Ag composite films are obtained by annealing FePt/Ag multilayer films. Upon annealing the layered structure is collapsed and L1₀ phase fct Fe₅₀Pt₅₀grains are formed. Giant magnetoresistance (GMR) effect is found in this system, which originates from the spindependent scattering of conduction electrons at the interface between FePt and Ag grains. The GMR ratio depends on the multilayer film structure and the annealing conditions, showing the correlation between the filmmicrostructure and GMR effect in granule-type composite films.
