Magnetic Resonance Properties of a Nanogranular NimC100 − m Film Structure

Resumo

Magnetic resonance properties characteristic of nanogranular film structure Ni_mC_{100 − m} with different concentrations m of its magnetic phase are studied. Samples are subjected to annealing at temperatures of 200 and 300°C. With tangential magnetization in the planes of films with m ranging from 70 to 89.8 at %, anisotropy is observed for the resonance field and the width of the absorption line. This anisotropy is explained by the uneven shapes of magnetic granules along different directions in the films.
