摘要: The Navy is investigating a reciprocating magnetic refrigeration concept that uses an active regenerator. geometry of this regenerator embossed ribbon configured formable material (generally rare earth metal) having reasonably large magnetocaloric effect at its Neel or Curie temperature. Several earths have shown increases in heat capacity their respective transition temperatures. Samples two metals, terbium and holmium, were subjected to 7-tesla change field over range temperatures the adiabatic temperature measured. Results indicated 10.3-°C 237 K 6.1-°C holmium 136 K. In addition, no thermal hysteresis was observed these materials near
