Abstract

Abstract: The electrical and magnetic properties of the perovskite La 2 /3 Ca 1 /3 MnO 3 are measured at the same time,in which colossal magnetoresistance and mechanism of double exchange are found.Transitions of insulator metal and paramagnetic-ferromagnetic are observed simultaneously,so interactions of electrical and magnetic in those materials are understood more easily.

Key words: CMR, insulator-metal transition, paramagnetic-ferromagnetic transition, double exchange
