Cs2NaAl1-xCrxF6: A family of compounds presenting magnetocaloric effect
Pedro, S. S.; Tedesco, J. C. G.; Yokaichiya, F.; Brandao, P.; Gomes, A. M.; Landsgesell, S.; Pires, M. J. M.; Sosman, L. P.; Mansanares, A. M.In this paper we explore the magnetocaloric effect (MCE) of chromium-doped elpasolite Cs2NaAl1-x,CrxF6 (x = 0.01 and 0.62) single crystals. Magnetization and heat capacity data show the magnetocaloric potentials to be comparable to those of garnets, perovskites, and other fluorides, producing magnetic entropy changes of 0.5 J/kg K (x = 0.01) and 11 J/kg K (x = 0.62), and corresponding adiabatic temperature chan...
