Abstract
A review is presented of three routes to control the anisotropy in amorphous alloys. These are field annealing, stress annealing and surface crystallisation. The aim is to highlight the differences in the magnitudes of the uniaxial anisotropies. The causes and consequences of the observed spread in easy axis direction within domains will be discussed. The magnetostrictive response of amorphous alloys will be discussed in terms of the controlling anisotropy. Devices using magnetostrictive response will be discussed, and the constraints imposed in device fabrication outlined.
