Abstract
The reptation and magnetic viscosity in &-Fe2O3tape as a function of an applied field is found by using a rotating sample magnetometer (RSM) which measures the decrease in remanent magnetization MR, as the sample spins in a field at different frequencies. A modified RSM is used to find the decrease in MRwhen a reverse field is repeatedly applied along a stationary axis. Reptation is found only when the sample rotates in a field. Magnetic viscosity effects peak at fields near the coercive field and scale with print-through in tapes.Keywords
