Abstract

Intragranular response intrinsic to the grains of a YBCO superconductor was isolated and was subjected to superimposed AC and DC magnetic field. Complex magnetic susceptibility results show that even with the addition of DC magnetic field to as high as 4.53 mT, vortices are not driven in the grains. The intragranular AC loss peak was explained and modelled through a mechanism of eddy current induced in the grains due to the time-varying magnetic field. The superimposed DC magnetic field was found to affect the resistance and penetration depth of the eddy current.
