Effect of deformation on magnetic properties of Heusler alloys

Abstract

Magnetic properties of Heusler alloys with the Ni54.4Mn17.6Ga26.2Si1.8 composition subjected to comprehensive isothermal forging have been investigated. It was found that comprehensive isothermal forging leads to a shift in the temperatures of structural and magnetic phase transitions toward low temperatures, a slight decrease in magnetization and magnetocaloric effect, as well as a qualitative change in the magnetic domain structure.
