Description

Anomalous voltage peaks have been observed below the critical current in dc transport measurements of superconducting YBCO coated conductors for specific contact arrangements. Using a simple concentrated constant-equivalent circuit, it is predicted that current redistributions due to non-homogeneities in the sample may explain the observed effect. (rapid communication)
