Reduction of hysteresis losses in the magnetic refrigerant Gd5Ge2Si2 by the addition of iron.
TL;DR: Although the addition of iron does not significantly affect the refrigerant capacity of the material, a greater net capacity is obtained when the hysteresis losses are accounted for and the iron-containing alloy is thus a much-improved magnetic refrigerant for near-room-temperature applications.
