Abstract

Magnetic and magnetocaloric properties of the intermetallic compound [formula omitted] have been studied. Temperature dependence of magnetization data shows that it exhibits ferromagneticlike bulk magnetic ordering at 14 K. For field changes [formula omitted] of 20 and 50 kOe, the maximum values of isothermal magnetic entropy change are found to be 9 and 17 J/kg K, respectively. For [formula omitted] and 50 kOe, the relative cooling powers are found to be 140 and 450 J/kg, respectively. At temperatures above [formula omitted], the spin fluctuations are found to affect the magnetocaloric properties of [formula omitted].
