Abstract

Ferromagnetic resonance (FMR) and torque curves have been measured in electrodeposited CoPd alloy films with composition ranged from Co₁₃Pd₈₃ to Co₄₅Pd₅₅. We show that the origin of the multimode structure of FMR spectra in these strongly magnetostrictive polycrystalline films can be satisfactory explained on the basis of the independent-grain-approach for a textured microstructure. The fourfold periodicity of the torque curves for the compositional range of 30-35 at.% is assumed to be originated by inhomogeneous distribution of the magnetization direction
