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.
