Abstract
Ferromagnetic resonance (FMR) measurements on Co films of thicknesses 10–100 Å grown on GaAs (110) and Au (111) substrates have been made as a function of dc magnetic field orientation in a plane perpendicular to the film. Experimental data were fitted by writing the energy density expression including uniaxial perpendicular anisotropy terms up to second order and bulk anisotropy terms. Co films grown on Au (111) substrates show consistently a higher uniaxial perpendicular anisotropy compared to those grown on GaAs (110) for the same thickness of Co. This is attributed to stress induced anisotropy due to a lattice mismatch between Au (111) and Co layers.
