摘要: In this article we report the thermodynamic investigations on Ericsson cycle with application RNi2 (R=Nd, Gd, Tb, Dy, Ho, and Er) series. Besides Zeeman exchange interactions, these compounds present an important contribution from crystalline electrical field interaction. The coefficient of performance refrigerant capacity was investigated under crystal influence. An optimum molar composite Er–Dy–TbNi2 proposed to work as material in temperature interval 7 22 K.
