Abstract

Superconducting magnetic shelding is very important for the application of superconducting devices such as dc and ac SQUID. The shields made of high Tc superconductors become one of their most important applications as it can work at liquid nitrogen temperature. Some results of magnetic shielding on YBaCuO plates1,2 , disc and hollow cylinders3,4,5,6 have been reported recently. But magnetic shielding fields are generally in the range of 1–2 mT. In this paper, we reported a YBaCuO superconducting tube with a bottom and its preparation, which can shield dc magnetic field up to 4 mT, as well as some results of magnetic flux trapping, and penetration and saturation for such sintered 1,2,3 bulk materials.
