Magnetic refrigeration

Magnetic algidity is a cooling technology based on the magnetocaloric effect. This address can be acclimated to attain acutely low temperatures (well beneath 1 K), as able-bodied as the ranges acclimated in accepted refrigerators, depending on the architecture of the system.

The aftereffect was aboriginal empiric by the German physicist Emil Warburg (1880) and the axiological assumption was appropriate by Debye (1926) and Giauque (1927).1 The aboriginal alive alluring refrigerators were complete by several groups alpha in 1933. Alluring algidity was the aboriginal adjustment developed for cooling beneath about 0.3 K (a temperature accessible by 3He refrigeration, that is pumping on the 3He vapors)
