Superconducting shield which has wall thickness over London penetration depth can realize zero field environment in principle. But in policrystal superconductor, to contact with Josephson junction between crystals, critical current density is smaller

Superconductors are expected to achieve perfect magnetic shielding, which will be useful for studies on neural activities of the brain especially in the lower frequency range down to DC. Operating in the environment of other noisy instruments and/or

A non-destructive evaluation (NDE) system for material damages of metals has been developed. The system enables very low magnetic field measurements by using a SQUID magnetometry system in a high-Tc superconducting shield. The shield has large intern

We have developed a cryostat for a large scale high-Tc superconducting shield enclosing a human body to measure biomagnetism. The cryostat has an interior space of ϕ 0.8 m × L2.8 m and cools a high-Tc superconducting shield ϕ 0.87 m × L2.4 m. The

The relaxation of a persistent current circulating in a toroid made of Bi2Sr2Ca1Cu2O8+x superconductor has been measured. The relaxation is described of the form of t-a and is explained by a equation deduced from a power-law characteristic of the I
