Abstract: Agiant magnetoresistance material La0.5Ba0.5MnO3 was prepared by hydrothermal method at 240 ℃ for 24 hours. The product was characterized by X-ray powder diffraction, differential thermal analysis-thermogravimetric analysis, chemical analysis, and iodometry. The compound crystallizes in a cubic system with cell parameters a =0.3913 nm and V =0.05990 nm3. The average valence state of manganese was 3.5, and the magnetoresistance (MR) is about 29% at 1 T.
Key words: La0.5 Ba0.5 MnO3, Hydrothermal systhesis, Giant magnetoresistance
