<p>A high Tc superconducting ceramics material is produced by a method in which a mixture of chemicals in suitable amounts is deposited on a surface in thin film form by sputtering, electron beam evaporation and so forth. The deposited mixture is then annealed to have superconducting property. Particularly, a magnetic field is applied to the mixture in a predetermined direction during depostion and/or annealing. By virtue of the application of magnetic field, the orderliness of molecular arrangement is enhanced and an elevated transition temperature Tc is obtained.</p> |
