The magnetic properties of glass-covered microwire with negative magnetostriction constant

The CoMnBSi composition cast amorphous glass-covered microwires with differ ent magnetostriction constant were investigated. Microwires with a wide ran ge of anisotropy field values and coercivity were produced from these alloy s using Ulitovsky-Taylor method. The internal and external stress dependenc e and influence of thermomagnetic treatments on the magnetic structure and propel ties were investigated and appropriate domain structures are suggest ed.
