<p>A high-temperature superconductive film having a flat surface and a composition composed of A, B, C, Cu, and oxygen where “A” is one or more kinds among Gd, Dy, Ho, Er, Tm, Yb, Lu, Y, “B” is one or more kinds among La, Nd, Sm, Eu, and “C” is expressed by Ba1-SSrS (where 0 ≤ S ≤ 0.50) and expressed by a chemical formula AxB(3-x-y)CyCuzO7-d (where x ≤ 0.99, y ≤ 1.99, 2.60 ≤ (x+y) ≤ 2.98, 2.70 ≤ z ≤ 3.30), (7-d) is a number sufficient to satisfy the requirement of the valences). According to the invention, “a high-temperature superconductive film having a flat surface and favorable superconduction characteristics” that is useful for manufacture of high-performance electronic devices and wire materials and can be manufactured stably irrespective of a minute variation of the film-forming condition.</p> |
