UNDERLYING LAYER OF ALIGNMENT FILM FOR OXIDE SUPERCONDUCTOR, METHOD OF FORMING SAME, AND DEVICE FOR FORMING SAME

摘要

A method of forming an underlying layer of an alignment film for an oxide superconducting conductor, includes arranging two or more kinds of targets along a lengthwise direction of a base material so as to face a surface of the base material; simultaneously irradiating an ion beam on surfaces of the two or more kinds of targets to deposit constituent particles of the targets on the surface of the base material in the order of the arrangement of the two or more kinds of targets; and forming a laminate in which two or more kinds of thin films are repeatedly laminated on the surface of the base material by passing the base material through a deposition region of the constituent particles a plurality of times so that the constituent particles of the targets are repeatedly deposited on the surface of the base material at each passage.
