superconducting thin film for the base material, the method of manufacturing the superconducting thin film and superconducting thin film

摘要

The effect of suppressing the diffusion of metal elements from the substrate is high, and the orientation of the forced alignment layer is improved. The superconducting thin film substrate (2) includes a substrate (10) containing a metal element, at least one transition metal element having a spinel crystal structure formed on the surface of the substrate (10), Mg And a bed layer (22) mainly composed of a non-oriented spinel compound composed of oxygen, and a rock salt type compound having a rock salt type crystal structure containing Mg and formed on the surface of the bed layer (22). A forced orientation layer (24) having axial orientation.
