Effects of doping rare earth element on Ln site of [Math Processing Error] (Ln=Nd, Sm and La) were examined from sintering behavior, structure and magnetic properties. Sintering reactions proceeded rapidly in order of [Math Processing Error] . This result can be explained by diffusivity of metal cation. Size of a-axis increased as following order of La [Math Processing Error] , 93K for [Math Processing Error] and 225K for [Math Processing Error] were obtained. This result coincides with change of Mn-O bond length causing by a-axis lattice constant.
