The invention relates to an MOD method for preparing an LSCO conductive film on biaxial texture NiW alloy, which belongs to the technical field of superconducting materials. The method comprises the following steps: dissolving strontium acetate, lanthanum acetate and cobaltous acetate into propionic acid step by step and adding acetylacetone to prepare precursor solution; coating the precursor solution on a biaxial texture NiW base band by a glue homogenizing machine; then carrying out pyrolysis processing and carrying out coating and pyrolysis processing again; and carrying out crystallization reaction. The prepared LSCO film has the thickness of 500-700nm, obstructs the diffusion process of a Ni element to a YBCO layer and favorably prevents the oxidation of an NiW substrate; and the electrical resistivity of the film, which is detected by a four-lead method can reach 1.1*10<-4>omega*m in a liquid nitrogen temperature zone. Compared with the traditional process, the invention reduces the number of buffer layers, thereby reducing the preparation process and the manufacture cost of a YBCO/buffer/NiW composite material.
