Time dependence of the magnetic moment of high-temperature superconductors
Abstract
The magnetic moment of high-temperature superconductors decreases logarithmically with time. It is shown that the temperature dependence of this relationship has a characteristic peak at a temperature of 30-40 K in a 500-G field. Assuming the existence of two types of pinning centers, it is shown that this dependence can be explained in the framework of Anderson's theory of the thermal creep of Abrikosov vortices.
