Phys. Rev. Lett. 67, 2099–2101 (1991)Influence of electric fields on pinning in YBa2Cu3O7-δ filmsReceived 24 July 1991; published in the issue dated 7 October 1991 Experimental evidence is provided that the pinning force and the critical current density of YBa2Cu3O7-δ films can be controlled by electric fields. This novel effect is attributed to field-induced changes of the density of mobile charge carriers in the superconductor. © 1991 The American Physical Society URL:
