Abstract: The magnetic properties of epitaxial Fe(001) films, prepared on GaAs(001) substrates by RF magnetron sputtering, were investigated by ferromagnetic resonance spectroscopy operating at Q-band (35 GHz). The in-plane angle dependence of the resonance fields showed four-fold magnetic anisotropy with an easy (hard) direction along [100] ([110]). The anisotropy constant was slightly smaller than the magnetocrystalline anisotropy constant of bulk Fe. Ferromagnetic resonance linewidths, caused by the magnetic damping of Fe films, were narrow (
