BaM films have a lot of advantage of chemical stability and mechanical stability as compared with a metallic thin film. In this paper, (Ba.Pb)M films have been prepared by using dc magnetron sputtering system and the dependences of their crystallographic characteristics and magnetic properties on oxygen pressure($Po_{2}$) were studied. The films prepared at $Po_{2}$ of around 0.02mTorr exhibit a fine particle-like structure and ${Delta}{ heta}_{50}$ is as small as $1^{circ}$. $Hc_{ot},;Hc_{//}$ and Ms of (Ba.Pb)M films are 700-800Oe, 200Oe and 180-230emu/cc, respectively.
