Large magnetic entropy change in a la0.8Ca0.2MnO 3 single crystal
(2004) In Journal of Magnetism and Magnetic Materials 272-276(3). p.2337-2339- Abstract
A large magneto-caloric effect is reported in a La0.8Ca 0.2MnO3 single crystal. The magnetic entropy change (ΔSM) reaches ∼7.25 J/kg K for an applied field of 5 T, which is very practical for magnetic refrigeration applications. Satisfactory agreement between the theoretical calculations on ΔSM derived in the molecular field approximation and the experimental dependency has been found.
