Popis:	We investigate the temperature dependence of the magnetization reversal process and of spinwaves in epitaxially grown (0 0 1)-oriented [Fe m /Au n ] 30 multilayers ( m =1, 2; n =1–6). Both polar magneto-optic Kerr effect and Brillouin light scattering measurements reveal that all investigated multilayers, apart from the [Fe 2 /Au 1 ] 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.
