The magnetic viscosity coefficient, S/sub 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/sub V/ depends strongly on the demagnetization processes of the films, S/sub V/ of the domain-lengthening magnetization process being larger than that of the domain-widening process.
