Abstract

The magnetocaloric effect (MCE) of DyTiO ₃ single crystal was studied by magnetization and heat capacity measurements. A large reversible MCE has been observed at the Curie temperature T _C of 65 K, which is related to a second-order magnetic transition from paramagnetic to ferrimagnetic state. The values of maximum magnetic entropy change can reach 9.64 and 15.88 J kg ^{- 1} K ^{- 1} for a field change of 2 and 5 T, respectively, with no obvious hysteresis loss in the vicinity of the Curie temperature. The magnetic transition and the origin of large MCE in DyTiO ₃ single crystal are discussed.
