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.
