magnetic refrigerator [mag′ned·ik ri′frij·ə‚rād·ər]

(cryogenics)

A device for keeping substances cooled to about 0.2 K, in which a working substance consisting of a paramagnetic salt undergoes a cycle of processes which approximates a Carnot cycle between a high-temperature reservoir consisting of a liquid-helium bath at 1.2 K and a low-temperature reservoir consisting of the substance to be cooled, and isentropic cooling of the working substance is accomplished by demagnetization.

NBC'S MASS-CONSUMPTION OLYMPICS by Daily News (Los Angeles, CA) Brown (1976) first constructed a regenerative magnetic refrigerator and showed that the use of a regenerative configuration can provide a no-load temperature span that is much greater than the adiabatic temperature change of the magnetocaloric material that is used to construct the regenerator.
