Abstract
The authors study magnetic properties of Heusler alloys with composition Ni54.4Mn17.6Ga26.2Si1.8 subjected to multiple isothermal forging. It is found that multiple isothermal forging shifts the temperatures of structural and magnetic phase transitions toward low values. Magnetization and the magnetocaloric effect are reduced slightly, and there is a qualitative change in the structure of the magnetic domain.
