Magnetocaloric effect and the change from first- to second-order magnetic phase transition in Pr0.7CaxSr0.3-xMnO3 polycrystalline compounds
The work presents the magnetocaloric effect and critical behavior of monoclinic polycrystalline Pr0.7CaxSr0.3-xMnO3 prepared by solid state reaction. The ferromagnetic-paramagnetic phase transition temperature decreases from 267, 202, 138 to 126 K with increasing doping concentration from x=0 to 0.3...
