A method of manufacturing the same and RE123-based oxide superconductor

摘要

In the method of RE123-based oxide superconductor, RE satisfy (i) and the following formula (1) and (2), Ba, and, to form a plume by irradiating a pulsed laser oxide target material including Cu The manufacturing method of the RE123-based oxide superconductor is characterized by depositing the RE123-based oxide superconducting film by holding the substrate in (ii) above the plume. 0.8 ≦ 2RE / Ba 1.0 ··· (1) 0.8 ≦ 3Ba / 2Cu 1.0 ··· (2) Here, Y, La, Nd, Sm, Eu, Gd, Dy, Ho, and, RE is any one or two or more of Er
