Specific heat of regenerative material RNi2 system

The RNi2 system, in which R is one of the heavy REEs, Dy or Er, is proposed as the regenerative material of Ericsson cycle magnetic phase transition refrigerator systems. RNi2 was prepared in solid solution and examined for temperature variation of specific heat up to 5 T. The system is found to hav...

Zusammenfassung:The RNi2 system, in which R is one of the heavy REEs, Dy or Er, is proposed as the regenerative material of Ericsson cycle magnetic phase transition refrigerator systems. RNi2 was prepared in solid solution and examined for temperature variation of specific heat up to 5 T. The system is found to have a large specific heat below 20 K, due to ferro-to-paramagnetic transition. The Curie temperature is noted to be controllable by changing the REE composition. (O.C.)
