FMR study of ultrahigh vacuum e‐beam evaporated Co 23 Cu 77 nanogranular films: Magnetotransport properties

The magnetic, magnetotransport and structural properties of Co 23 Cu 77 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 G...

description The magnetic, magnetotransport and structural properties of Co 23 Cu 77 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.
