ABSTRACT

The structural and magnetic properties of as-cast and annealed Co-rich microwires in a glass shell with the diameter of D = 125 μm and the diameter of the amorphous metallic core of d = 50-90 μm, produced by the modernized Ulitovsky–Taylor method, have been investigated. The saturation field HS and the coercive force HC of the samples were found to depend on annealing temperature. The near-surface values of HS and HC were discovered to be larger than the bulk ones. The obtained experimental data were explained by the structural features of the microwires under study.
