Cooling by Adiabatic Magnetization

Phys. Rev. Lett. 23, 307 – Published 11 August 1969

Abstract

We report 5.5°K cooling at 20°K in the ferrimagnet ytterbium iron garnet accompanying an increase of magnetic field. The cooling abruptly ceases at the phase boundary between a collinear and canted sublattice configuration. A cooling of 10°K at 18°K and 3.7 °K at 6°K was observed in dilute ytterbium iron garnet.
