摘要：
A superconductive oxide material having an infinite layer structure and having the following formula:A.sub.p B.sub.q Cu.sub.2 O.sub.4.+-.rwherein A and B are different and each represent an element selected from lanthanoid elements and elements belonging to Groups IA, IIA and IIIA of the Periodic Table, p is between 0.9 and 1.1, q is between 0.9 and 1.1 and r is between 0 and 0.6. The oxide material has a crystal structure belonging to a tetragonal system of P4/mmm and 1-123 having the following lattice parameters:3.8.ANG..ltoreq.a.ltoreq.4.0.ANG.7.6.ANG..ltoreq.c.ltoreq.8.0.ANG.or to an orthorhombic system of Pmmm and I-47 having the following lattice parmeters:3.8.ANG..ltoreq.a.ltoreq.3.95.ANG.3.82.ANG..ltoreq.b.ltoreq.4.0.ANG.7.6.ANG..ltoreq.c.ltoreq.8.0.ANG..
