Abstract

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