Abstract

In this work, we have studied the magnetocaloric effect (MCE) of Ho(Co 1-xNix)2 for 0≤x≤0.1. HoCo2 exhibits a first-order ferrimagnetic to paramagnetic transition at T C=78K. The substitution of Ni for Co lowers TC of the compound. While the character of the transition and the MCE changes from a first-order type to a second-order type by the Ni substitution, the large MCE at around TC is maintained up to x=0.1. The origin of the large MCE of the compounds is discussed.
