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
