Magnetocaloric materials: the search for new systems

Abstract

The prospect of efficient solid state refrigeration at room temperature is driving research into magnetic cooling engine design and magnetic phase transition-based refrigerants. In this Viewpoint an Ashby-style map of magnetic refrigerant properties is constructed, comparing popular materials with limits derived from an idealised first order transition model. This comparison demonstrates the potential for new magnetocaloric material systems to be established through structural control and optimisation at the atomic-, nano- and micro-scale.

6 pages, 2 figures (both in colour). Section 2.2 on cooling power is an online Appendix in published version in Scripta Materialia. Version 5: corrected typo in the Figure 2 caption
