Influence of structural-phase transition on the magnetocaloric effects of lanthanum manganites
We studied the magnetic entropy change (Δ S m) of the perovskite manganites La 0.7Ca 0.3− x Sr x MnO 3 ( x = 0.12 , 0.135, and 0.15). Effect of orthorhombic–rhombohedral structural transition, coinciding with the ferromagnetic–paramagnetic (FM–PM) phase transition, on the Δ S m is observed. The stru...
