Magnetocaloric effect of the Tb1-xYxNiAl and TbNiAl1-yIny series

Abstract

We have studied the development of the magnetocaloric effect in the (Tb,Y)NiAl and TbNi(Al,In) series as determined from magnetization measurements. The transition from antiferromagnetic order in TbNiAl to ferromagnetic order in Tb0.7Y0.3NiAl is accompanied by increase of the maximum entropy change.

In the TbNi(Al,In) series, the change of uniaxial anisotropy in TbNiAl to the easy-plane anisotropy in TbNiIn leads to broadening of the magnetocaloric effect accompanied with large increase of the relative cooling power.
