Influence of electric fields on pinning in YBa2Cu3O7- films
Abstract
Experimental evidence is provided that the pinning force and the critical current density of YBa2Cu3O7- 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.
