Abstract

The invention relates to the technical field of yttrium barium copper oxide coating conductors, in particular to a high-performance REBCO multilayer film, application and a preparation method for the high-performance REBCO multilayer film. The high-performance REBCO multilayer film is composed of a REBCO thin film layer and an STO interlayer. The invention further relates to the application of the high-performance REBCO multilayer film during preparing of a high-temperature superconductive belt material and relates to the preparation method for the high-performance REBCO multilayer film. The preparation method comprises the following steps that an IBAD-MgO base belt plated with an isolated layer is taken, and the high-performance REBCO multilayer film is prepared through a multi-target multi-channel pulse laser method. The prepared high-performance REBCO multilayer film prepared has a pure C-axis orientation, a smooth compact surface and a high critical current density, and the critical current density reaches up to 5 MA / cm<2>. The REBCO multilayer film has high critical current under a self field or a magnetic field, has the high binding force, can meet the application requirements for a superconducting cable and the like and is suitable for industrialization production.
