We report on ferromagnetic resonance and torque curves measurements in electrodeposited CoPd alloy films with composition ranged from Co13Pd87 to Co45Pd55. We show that the origin of the multimode structure of ferromagnetic resonance spectra in these strongly magnetostrictive polycrystalline films can be satisfactorily 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% of Co seems to be originated by the microstructure features which lead to a distribution of the easy axis directions within the films.
