Abstract
This letter reports on the magnetocaloric properties of Sm0.52Sr0.48MnO3 single crystal. A magnetic field of only 1 T yields a change in the magnetic entropy by 5.9 J/(kg K) at TC (=124 K), which is higher than those observed in several other perovskite manganites and rare earth alloys of comparable TC. This change originates from a sharp magnetization jump, associated with a first-order metamagnetic transition. Such a large change in entropy at a low magnetic field makes this material useful for magnetic refrigeration.
