Abstract

The magnetic, magnetotransport and structural properties of Co₂₃Cu₇₇ granular thin films (7–43 nm) have been investigated using ferromagnetic resonance (FMR) and high-resolution XRD techniques. Co particles possess a crystalline fcc structure in the investigated films. A correlation between the GMR effect and the anisotropy field has been found, which increases with increasing film thickness. Temperature-dependent FMR measurements revealed a blocking effect, which results from the competition of long range dipole–dipole interaction and anisotropy fields of Co particles.
