Abstract: In this paper we explore the magnetocaloric effect (MCE) of chromium-doped elpasolite Cs2NaAl1−xCrxF6 (x = 0.01 and 0.62) single crystals. Our 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 changes of 4 K and 8 K, respectively. These values are for a magnetic field change of 5 T at a temperat… Show more
