Abstract
A giant magnetoresistance material La0.5Ba0.5MnO3 was prepared by hydr othermal method at 240 degrees C for 24 hours, The product was charact erized by X-ray powder diffraction, differential thermal analysis-ther mogravimetric analysis, chemical analysis, and iodometry, The compound crystallizes in a cubic system with cell parameters a = 0. 391 3 nm a nd V = 0. 059 90 nm(3), The average valence state of manganese was 3. 5, and the magnetoresistance (MR) is about 29% at 1 T.
