Abstract

Excellent shielding performance can be expected in a superconducting magnetic shield because the magnetic flux are completely removed from inside by Meissner effect. Thus, superconductors can be used as a shield for magnetic noise during very weak magnetic measurements, such as required for biomagnetics. Discovery of the high-Tc superconducting material brought about a complete change in the application of superconductors. Because the operation of superconductor at the liquid nitrogen temperature has become possible, large superconducting magnetic shields have become realistic.
