Magnetic ordering and anisotropies of atomically layered Fe/Au(001) multi-layers

  • We investigate the temperature dependence of the magnetization reversal process and of spinwaves in epi-taxially grown (001)-oriented [Fem/Aun]30 multilayers (m = 1, 2; n = 1- 6). Both polar magneto-optic Kerrr effect and Brillouin light scattering measurements reveal that all investigated multilayers, apart from the [Fe2/Au1]30-sample, are magnetized perpendicular to the film plane. The out-of-plane anisotropy constants are obtained. At high temperature, the magnetization curves are well described by an alternating stripe domain structure with free mobile domain walls, and at low temperature by a thermal activation model for the domain wall motion.
