Abstract

The lock-in transition on good-quality over-doped Tl2Ba2CuO6 single crystal was investigated. The observed sharp drop, a dip and a peak together in the flux flow resistivity ρ(θ) as the magnetic field angle θ with the c-axis approaches 90° have been ascribed to vortex phase transitions of different types. A demonstration of the inadequacy of the two models of the angular dependence of the upper critical fields to explain this phenomenon is presented here.
