Abstract

Magnetic properties and magnetocaloric effects of the intermetallic compound ErCoAl, crystallizing in the hexagonal MgZn₂-type structure, have been investigated. This compound shows second-order ferromagnetic transition with Curie temperature T_C=16 K. Around T_C, the maximum entropy change and relative cooling power are estimated to be 11.0, 15.5 and 18.5 Jkg^-1K^-1 and 151, 284, and 433 Jkg^-1 for a field change of 30, 50, and 70 kOe, respectively. These experimental results suggest that ErCoAl could be an appropriate candidate for magnetic refrigerant working at the temperatures near 20 K.
