Abstract
The magnetic anisotropy and magnetoelastic properties in epitaxial iron films prepared by DC magnetron sputtering on single crystal GaAs (001) substrate and covered by a protective Si layer have been investigated by means of the ferromagnetic resonance (FMR), strain modulated ferromagnetic resonance (SMFMR) and magneto-optical Kerr effect (MOKE). It has been shown that the uniaxial and cubic anisotropy constants as well as two magnetoelastic constants strongly depend on the thickness of the film. The surface parts of the cubic anisotropy and magnetoelastic constants have been obtained.
