Abstract

The influence of the demagnetization field on the magnetic after-effect of Co-Cr media is discussed. The demagnetizing field of as-sputtered Co-Cr was changed into block-shaped micro structures by lithographic processes. This process does affect the shearing of the perpendicular hysteresis curve but not the intrinsic magnetic properties. A linear relation was obtained between the coefficient of magnetic viscosity and the slope of the hysteresis curve
