MAGNETIC PROPERTIES OF AMORPHOUS ALLOYS ON THE BASE OF HEAVY RARE-EARTH METALS

Amorphous alloys of heavy rare-earth metals with iron and cobalt, intermetallic compounds are considered in the paper aiming at the experimental and theoretical investigation of magnetic structures, phase transitions, exchange interactions in rare-earth amorphous alloys in a wide range of fields, temperatures, pressures and concentrations. As a result models for the description of magnetic structures in amorphous rare-earth alloys under the influence of a field, temperatures and pressures have been elaborated. New phase transitions have been detected. The model, describing magnetization processes in amorphous systems with a quided anisotropy, has been developed. Systematic investigations of magnetization processes, phase transitions, crystallization processes have been held. Measurement of the gigantic magnetostriction, the magnetization dependence on a pressure, the effect the axis reorientation of the light magnetization have been also held. The paper results may be used for the development of new magnetic materials for sensors and actuatorsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
