Abstract
We report the magnetocaloric effect in the La0.67Ca0.33Mn0.9Fe0.1O3La0.67Ca0.33Mn0.9Fe0.1O3 perovskite. A peak in the magnetic entropy change [ΔSM(H)] versus T curve, centered around 113 K, has been observed. −ΔSM(H) increases with an increasing applied magnetic field. The maximum value of −ΔSM(H) for ΔH = 3 T field has been found to be 1.18 J kg−1 K−1 at 113 K with a relative cooling power of ∼87 J kg−1 and a quite broad operative temperature range 65–160 K. The hysteresis loss has been found to be very small. A large magnetocaloric effect with a relatively low material cost makes the studied perovskite attractive for magnetic refrigeration.
