Entropy and magnetic properties of Ni-Mn-In magnetocaloric materials

ORAL

Abstract

Materials showing the magnetocaloric effect (MCE) have been a source of growing interest because of their potential for an environmentally friendly and energy efficient refrigeration technology. Recently, alloys based on Ni-Mn-Z (Z$=$In, Sb, Sn) have been reported to show a large MCE across the martensitic transformation where a first order structural transition is coupled to a magnetic transition. In this study, Ni-Mn-In materials with compositions NiMnIn, NiMnInand NiMnInwere analyzed both through magnetization and field-dependent calorimetry. For measurements across the first-order transformation region, we designed a modified method for relaxation calorimetry. Based on these measurements we identified individual contributions to the entropy change, including an antiferromagnetic state at low temperatures and a large change at the first order transition. The NiMnInresults also include a large anomalous nonmagnetic contribution.We will conclude by discussing the relative cooling power, and the prospects of these materials for practical applications.
