The concentration dependence of the Curie temperature of the colossal magnetoresistance perovskite La1-xCaxMnO3

The concentration dependence of the Curie temperature of the colossal magnetoresistance perovskite La1-xCaxMnO3 was studied. A phenomenological model was used for interacting electronic and magnetic-phase transitions. The results shows that in the doping range most of these perovskites undergo a paramagnetic (PM) insulator/semiconductor to ferromagnetic (FM) metal phase transition upon cooling.
