<P>PROBLEM TO BE SOLVED: To provide a production method for producing, at a low cost, a base material for an oxide superconductor, which is equipped with a CeO<SB POS="POST">2</SB>cap layer having good crystal orientation, and to provide a base material for an oxide superconductor, which is obtained by using the method, and also to provide an oxide superconductor. <P>SOLUTION: The production method of the base material for an oxide superconductor is characterized by irradiating a target with any one of a third higher harmonic (with a wavelength of 355 nm), a fourth higher harmonic (with a wavelength of 266 nm) and a fifth higher harmonic (with a wavelength of 213 nm) of a YAG laser light so that the energy density on the target is 6 J/cm<SP POS="POST">2</SP>or more to beat out or evaporate particles constituting the target and to deposit the particles on the surface of an intermediate layer formed in an upper part of a base material, and thereby forming a CeO<SB POS="POST">2</SB>cap layer on the intermediate layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
