Abstract
Magnetic shielding properties were measured at 77 K in YBaCuO superconducting plates prepared by melt processes. Melt processed YBaCuO has a high Jc value, hence the material is promising for the application to magnetic shielding in a relatively high magnetic field. The shielding plate with 1 mm in thickness reduces an external magnetic field of 7.1 mT to a minimum value of less than 0.1 mT. A plate which consists of small samples in a tile shape is considered to be realistic to design a large shielding plate, and a laminated plate can enhance the shielding properties. The touching part in one layer does not extend from the bottom to the top of the shielding plate in three layers. The laminated plate in three layers reduces an applied magnetic field of 14.4 mT to an average value of about 8 mT.
