Magnetic heat pumps utilize entropy reductions which occur upon magnetization (magnetocaloric effect) in thermodynamic cycles. Magnetic equivalents of Brayton and Ericsson (or Stirling) cycles are possible. Magnetic heat pumps with gadolinium working material perform significantly better than conventional equipment. Working materials appropriate for industrial heat pump applications (400 to 500 K) have been identified, but performance is not as good as with gadolinium. When better performing hightemperature materials are identified, feasible industrial magnetic heat pumps should be possible.
