Abstract

In this paper, the investigation into the validity of the Snock limit in such random anisotropy composite materials requires knowledge of the local magnetization values. In plane Ferromagnetic Resonance was used to probe the local magnetization (M/sub s/) and in plane anisotropy profiles. The resonance fields were used to obtain the local values of M/sub s/ by employing the Kittel formula.
