Magnetic Properties of CeO₂ Doped YBCO Oxides

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.
