Abstract

rs are Delta alpha/alpha = 0.28% and Delta c/c = 0.64% on cooling. A substantial change in the 4f and conduction electron hybridization, giving rise to an increased integrated DOS, occurs when the high temperature phase transforms to the low temperature phase. A moderate magnetocaloric effect at T-N (Delta S-M = 6.5 J/kg K and Delta T-ad = 4.5 K for Delta H = 50 kOe) has been measured using both magnetization and heat capacity data. (C) 2014 Elsevier B.V.
