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.
