"palladium-based (Pd) MMSMA that exhibits low energy loss. Even at low temperatures of about 100 K this energy loss was lowered to only about 1/100 when compared to existing MMSMAs... pulsed high magnetic fields liquid-helium temperature... increased energy loss as temperature dropped... better lattice compatibility for phase transformation, crystals within structures change easier, smaller energy loss, large magnetostriction low temperatures... magnetic sensors and actuators"
