The influence of low magnetic fields parallel to the c-axis on the vortex-antivortex (v-a) distribution in one BSCCO crystal and in one oriented film is studied by examining the changes of the non-ohmic response near the superconducting transition. The obtained results confirm the non-external magnetic origin of a v-a configuration and are interpreted by a losening and a depairing of the v-a couples in a way similar to that produced by the temperature. Phenomenological dependences of the two effects are proposed.

Abstract
The influence of low magnetic fields parallel to the c-axis on the vortex-antivortex (v-a) distribution in one BSCCO crystal and in one oriented film is studied by examining the changes of the non-ohmic response near the superconducting transition. The obtained results confirm the non-external magnetic origin of a v-a configuration and are interpreted by a losening and a depairing of the v-a couples in a way similar to that produced by the temperature. Phenomenological dependences of the two effects are proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
