PURPOSE:To provide the title superconductor small in Jc level drop even on magnetic field application. CONSTITUTION:The objective superconductor can be obtained by mixing (A) a Ln-Ba-Cu-0-based [Ln is lanthanoid element (except Ce, Pr, Pm and Tb) and/or Y] oxide and (B) Ln-Ba-Al-Cu-O-based [Ln is lanthanoid element (except Ce, Pr, Pm and Tb) and/or Y] oxide followed by calcining. |
