Abstract
An oxide superconducting element is formed on a substrate by a layered structure formed of oxide superconducting thin-film and a non-superconducting thin-film layers. The element is a superconducting regular current interval voltage step element. The current-voltage characteristic curve in a magnetic field has a voltage step being generated at regular bias current intervals. The layered structure is formed by depositing alternately M′Ba Cu O (M′ is one or a combination of more than two elements of Nd, Sm and Eu) and M″Ba Cu O thin-films (M″ is either Pr or Sc, or a combination of the two elements).
