摘要：

The synthesis and characterization of the magnetic materials of La(0.8)Ba(0.2)Mn((1-x))TixO(3) system (x = 0 - 0.7) by mechanical alloying process have been performed. The refinement results of x-ray diffraction pattern showed that the doping concentration (x < 0.5) was a single phase, which has a structure monoclinic (I12/a1). The microstructure analysis showed that the particle shapes was polygonal with the varied particle sizes distributed homogeneously on the surface of the samples. We concluded that the maximum number of titanium atoms substituting manganese atom is around x similar to 0.43 without changing the structure of this system..
