JMMM 28 (1982) 299-304 Single crystal Fe films grown on GaAs substrates W. Wettling, R.S. Smith, W. Jantz and P.M. Ganser Fe films epitaxially grown on GaAs substrates have been prepared and investigated. On {110} surfaces, single crystal films are obtained. The magnetic properties are investigated using ferromagnetic resonance and inelastic light scattering from surface magnons. A satisfactory interpretation is obtained by assuming cubic and growth-induced tilted uniaxial anisotropy.
