다국어 초록 (Multilingual Abstract)

- The electromagnetic effect observed in a BiSrCaCuO superconductor was studied. The electromagnetic properties of a Ag2O doped BiSrCaCuO superconductor and an undoped superconductor were evaluated to investigate the contribution of the pinning effect. It was confirmed experimentally that a large amount of magnetic flux was trapped in the Ag2O doped BiSrCaCuO than that in the undoped one, indicating that the pinning centers of magnetic flux are related closely to the occurrence mechanism of magnetic phenomena. It was considered that by adding Ag2O, the area where normal conduction takes place increases and the magnetic flux penetrating through the sample increases. It also was considered that Ag2O acts to increase pinning centers of magnetic flux.
