Abstract

Some FeNi‐Ag granular films of composition Fe11.43Ni6.35Ag82.22 (sample A) and Fe7.62Ni16.4Ag75.98 (B) were prepared by using rf magnetron sputtering, and once deposited were rapidly annealed at 600, 650, and 750 °C. All samples displayed giant magnetoresistance. The zero‐field‐cooled and field‐cooled processes evidence the segregation of ferromagnetic particles with a broad size distribution. The temperature and magnetic field dependence of the resistance is analyzed. The magnetoresistance follows a Hn law at high fields and it decays from its maximum value with a Tm behavior, with m approaching 1 at high fields.
