In the research, Y-Ba-Cu-O (YBCO) thick film was fabricated to form a highly sensitive magnetic sensor, constructed to maintain the superconducting state at the boiling point of liquid nitrogen (77.4 K). Superconducting film will, in general, break t

Idealized magnetic shielded vessels can be realized by use of high-critical temperature superconductors (HTS). It is, however, generally, very difficult to evaluate the limit of the value of magnetic shielding and the fluctuation of the magnetic flux
