Abstract

Recently, bulk-type high-T_c superconductors (HTSs) having a characteristic of critical current density over 10⁴ A/cm² in liquid nitrogen (77 K) and at 1 T have been produced. They are promising for many practical applications such as a magnetic bearing, a magnetic levitation, a flywheel, a magnetic shielding, and others. In this research, we propose a magnetic circuit that can be used as a magnetic shield for several superconductors as an application of the HTS. It is a closed magnetic circuit by means of a toroidal core. Characteristics of the magnetic circuit surrounded with HTSs are evaluated and the possibility is examined. Because the magnetic circuit of the ferrite core is surrounded with HTSs, the magnetic flux is shielded even if it leaks from the ferrite core.
