Critical temperature measurement method of composite superconductors

摘要

The critical temperature (T-c) is one of the most important properties in applications of superconductors. There are a lot of test methods to measure T-c of superconductors and therefore the standardization of the measurement method of T-c is needed. For those demands the draft of T-c measurement method was prepared by various organizations and committees in Japan. The outline of the method was the resistance method using a 50% resistance criterion, which is applicable to both metallic and oxide composite superconductors in industrial uses. The draft was submitted to IEC/ TC90 and certified as a new work item proposal. (C) 2001 Elsevier Science B.V. All rights reserved. [References: 1]
