A process for producing a superconducting transition of high-tc oxide superconductor

摘要

Improvement in a process for fabricating a superconducting junction by depositing successively a first oxide superconductor thin layer, a non-superconducting intermediate thin film layer and a second oxide superconductor thin film layer on a substrate in this order.;In the ivention, the non-superconducting intermediate thin film layer is composed of MgO and the substrate is heated at a temperature between 200 and 400°C during the non-superconducting intermediate thin film layer is deposited.
