Abstract
Using a zero-magnetostriction amorphous alloy, we have shown first, that the kinetics and magnitude of the field-induced anisotropy are independent of the axis of the anisotropy in the plane of a disk sample, and second, that the kinetics of reorientation of the anisotropy from one axis to another at constant temperature are also independent of the axes of the anisotropies. Consideration of the behavior of the vector components of the anisotropy during reorientation suggests that if the observed bulk anisotropy can be regarded as due to the sum of many local anisotropy units, then the reorientation takes place by the decay of one set of anisotropy units and the independent growth of another set.
