The effect of the Initial Layer on the Reversal Mechanism in CoCr Layers

The dependence of OR, H/sub c/, and hysteresis loss is measured as functions of the angle with the applied field (H/sub a/) as a parameter. It is reported that with increasing H/sub c/ perpendicular to /H/sub k/ values the orientation direction of the magnetization gradually changes from in-plane (OR/sub perpendicular to /=0.7) to perpendicular (OR/sub perpendicular to /=3.9). The angular dependence of H/sub c/ is closely related to the value of H/sub a/. It was found that H/sub c//H/sub c perpendicular to / drastically decreases at H/sub a/=H/sub c perpendicular to max/ (159 kA/m) with decreasing H/sub a/. The influence of the demagnetizing field on the angular dependence of the magnetic behavior in CoCr films is also examined.
