Study of GdCrO4 2017 Access copy available to the general public Unrestricted The zircon polymorph of GdCrO4 has a large magnetocaloric effect over a wide temperature range, with |¿ST| > 20 J/kg·K from 6 K to 34 K, for a magnetic field of 9 T. This unusual behaviour is very interesting on magnetic refrigeration applications, for liquefying H2 or natural gas. The mean-field approach explains that it is due to the weaker Gd-Cr magnetic exchange relative to the Cr-Cr one, while the Gd-Gd exchange is negligible. This possibility has not been sufficiently studied and opens an interesting strategy to design more efficient materials for magnetic refrigeration. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Tomasi, Corrado Saez-Puche, Regino Dos Santos-Garcia, Antonio J.
