Different cation deficiency doped La0.85Ba0.1MnO3 and La0.9Ba0.05MnO3 and La0.9Ba0.1Mn0.95O3 and stoichiometric La0.9Ba0.1MnO3 polycrystalline bulk samples were synthesized at 1500 degrees C, the ac magnetic susceptibility, resistivity and magnetic resistance (MR) of the samples were tested, and it is found that stoichiometric phase La0.9Ba0.1MnO3 sample have the highest ferromagnetic transition temperature T-c, and La0.9Ba0.05MnO3 sample have the lowest ferromagnetic transition temperature T-c. La0.85Ba0.1MnO3 sample have the largest magnetic resistance (MR), except La0.9Ba0.05MnO3 sample, the other samples have the same MR peak temperature.
