Magnetocaloric effect in random magnetic anisotropy materials

In this letter we report the results of entropy variations in random anisotropy magnets composed of TbxY1−xAl2, with x=0.15, 0.20, 0.25, 0.35, 0.40, and 0.50. We discovered large entropy variation associated with the spin glass to paramagnetictransition. Both temperature transition and entropy chang...
