The invention discloses a superconductor-insulator-metal heterogeneous film material which is of a laminated structure. The superconductor-insulator-metal heterogeneous film material comprises a metal hafnium base layer, a hafnium pentatelluride film structure layer and a hafnium tritelluride film structure layer, and the laminated structure is expanded in a two-dimensional plane. A preparing method includes the steps that a proper amount of high-purity hafnium is evaporated and deposited to the surface of the transition metal hafnium base layer in a vacuum environment; annealing treatment is conducted so that deposited tellurium atoms and metal hafnium atoms on the base interact with each other to form a hafnium pentatelluride two-dimensional orderly crystalline film-shaped structure; and annealing treatment is further conducted, the surface of the formed hafnium pentatelluride two-dimensional orderly crystalline film-shaped structure is subjected to the structure change again to form hafnium tritelluride, finally, the hafnium tritelluride-hafnium pentatelluride-metal hafnium two-dimensional laminated structure is formed, and the superconductor-insulator-metal heterogeneous film material is obtained. The preparing technology is relatively simple, defects of the obtained heterogeneous-structure film are few, an interface is not likely to be polluted, and the quality of the heterogeneous-structure film is improved.
