Abstract
The electromagnetic characteristics in YBCO superconductor were studied.
Electromagnetic properties of CeO2 doped and undoped YBCO superconductor was evaluated to
investigate the effect of pinning center on the magnetization and magnetic shielding. It was
confirmed experimentally that a large amount of magnetic flux was trapped in the CeO2 doped
sample than that in the undoped one, indicating that the pinning centers of magnetic flux are related
closely to the occurrence mechanism of the magnetic effect. It was concluded that the
electromagnetic characteristics arose from the interaction between the trapped magnetic flux and
weak link of the filament formed in the superconducting bulk.
