Abstract
The present invention provides a tape-form oxide superconductor having a high degree of c-axis alignment and in-plane alignment and an improved Jc value. On a tape-form metal substrate which is non-magnetic or weakly magnetic and has high strength, there are sequentially formed a first intermediate layer wherein YSZ or Zr Rx O particles are deposited from a target with ion irradiation from a direction inclined to the metal substrate, a second intermediate layer of CeO or Y O is formed and an RE Ba Cu O superconducting layer is formed by coating metalorganic salts containing F, followed by thermal decomposition.
