Abstract
A process for preparing a-axis oriented thin film of oxide superconducting material on a substrate by two steps. In the first step, an under-layer of an oxide superconducting material is deposited on the substrate under such a condition that the substrate is heated at a temperature which is suitable to realize an a-axis orientation of crystal of the oxide superconducting material. In the second step, an upper-layer of the same oxide superconducting material is deposited on a surface of the resulting under-layer under such a condition that the substrate is heated at a temperature which is lowered by 10.degree. to 100.degree. C. than the temperature which is used in the first step.
