Magnetoimpedance detection of the structural relaxation of amorphous ferromagnetic alloys

The possibility of using magnetoimpedance spectroscopy for detecting the structural relaxation of amorphous ferromagnetic alloys is considered. Studies of cobalt-based amorphous wires show the high sensitivity of the method to structural relaxation processes that occur at 100–200°C and the possibility of recording not only integral changes in the properties of materials under mild heat treatment conditions but also for detecting these changes layer by layer.
