<p>The superconductivity properties of superconducting compounds are controlled or maintained by active external electrochemical intervention. The superconducting compound forms one electrode (12) in the electrochemical cell (10). A counterelectrode (14) and the superconducting compound electrode (12) are in contact with an electrolyte (16) and a potential is applied between the counterelectrode (14) and the superconducting electrode (12). The cell is operated at a temperature near the expected transition temperature of the superconducting material. The potential applied between the electrodes is selected to control a property such as transition temperature. In a preferred embodiment, a superconducting material such as Ba2YCu3O7-x serves as an anode (12) and a counterelectrode (14) such as a mercury-mercuric oxide reference electrode serves as a cathode. Suitable oxygen-bearing electrolytes are ozone and trifluoronitrosomethane. In another embodiment, a superconducting cuprate material serves as a cathode and the electrolyte is copper-bearing.</p> |
