Abstract: Magnetic and magnetocaloric properties of the intermetallic compound Er(3)Co have been studied. Temperature dependence of magnetization data shows that it exhibits ferromagneticlike bulk magnetic ordering at 14 K. For field changes (Delta H) 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 Delta H=20 and 50 kOe, the relative cooling powers are found to be 140 and 450 J/kg, respectively. At temperatures above T(ord), the spin fluctuations are found to affect the magnetocaloric properties of Er(3)Co. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3367887]
