Abstract

The magnetic viscosity coefficient, S_V, of RF sputtered FeTb films was measured at fields between -5000 and +200 Oe at room temperature. The films, which are amorphous, have a perpendicular anisotropy and a typical stripe domain structure. S_V depends strongly on the demagnetization processes of the films, S _V of the domain-lengthening magnetization process being larger than that of the domain-widening process
