Abstract

Analysis of resistive transitions of YBa₂Cu₃O₇ crystals reveals a scaling behavior which identifies the vortex-depinning critical field H_cp, hence the crossover in behavior from flux creep to flux flow. The inferred H_cp for YBa₂Cu₃O₇ crystals closely approximates the magnitude and temperature dependence of H_cp derived from penetration length measurements of thin films.
