✦ Synopsis

Abstract

The magnetic anisotropy energy and the resonance linewidth of epitaxial Fe~3~Si grown on GaAs(001) is studied by ferromagnetic resonance (FMR) technique. For a nearly stoichiometric sample (25.5% Si‐content) a clear fourfold anisotropy is observed which is modulated by a small contribution of an uniaxial in‐plane anisotropy. This uniaxial component is found to increase with the Fe concentration in the intermetallic compound. The samples show an exceptional narrow resonance linewidth of only 17 Oe at 9 GHz excitation frequency confirming the very high structural quality. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
