Abstract

Abstract: La_1-δ Mn_1-δ O₃compounds were prepared by the sol-gel technique. The effect of sintered condition on the crystal structure, magnetic property, conductivity and magnetoresistance for La_1-δMn_1-δO₃was investigated. It was found, for the first time, that there exist two peaks in the R-T curve for the sample sintered at 1473 Kfor 24 hours.

Key words: Colossal magnetoresistance(CMR), Metal-insulator transition, Sol-gel technique, Double exchange interaction
