Abstract

The structure and magnetic properties of Nd0.5Pb0.5-xSrxMnO3 (0 less than or equal to x less than or equal to 0.4) manganites were systematically investigated. Significant changes in Curie temperature and metal-insulator (MI) transition temperature of the samples were observed. All samples exhibited a transition from paramagnetic semiconducting to ferromagnetic metallic state. Curie temperature T-C and the MI transition temperature T-p increased with increasing Sr content. We attributed these behaviours to the enhancing of both the double exchange mechanism and the Jahn-Teller electron-phonon coupling.
