Abstract

The magnetization reversal process in the surface and volume areas of Co-rich glass covered microwires has been investigated. The value of the helical anisotropy has been determined in two wires with different thickness of glass covering. The dependence of the coercive field on the frequency of the external axial magnetic field was studied in the surface and volume of the microwires
