Effect of a magnetic field on the critical current density of YBa2Cu3O(7-x) ceramic
Abstract
Induction methods for measuring the critical current of high-temperature superconductor are described with particular reference to the superconducting ceramic YBa2Cu3O(7-x). For weak magnetic fields, where the well-known Campbell method is inapplicable, a method is proposed whereby the critical current is determined from the magnetic moment, measured by the induction method. This method also makes it possible to determine the critical current of the individual particles of superconducting ceramic powders.
