摘要：

A technology has been developed for fabrication of magnetic shields and other high technological wares of superconducting yttrium-barium-copper ceramic by hot casting under pressure. The method enables to form wares of complex configurations and different sizes without any additional machining. The method of hot casting under pressure allows to obtain superconducting shields with a fair homogeneity of the critical field over the shielding length. At working temperature 77,4K the shields have a threshold screening field H(c)* about 1.5 mT, high screening factor (S>10(4)) and low intrinsic noise level (< 10(-6)mT).
