Description/Abstract

Using high angular resolution magnetic measurements we studied YBa2Cu3Oy single crystals with different oxygen contents (6.76y<7.00), for the magnetic field direction closely parallel to the crystal CuO planes. Our data show that the intrinsic pinning resulting in a smectic phase is a dominant factor at low temperatures. Near Tc the point defect pinning prevails and induces a transition from the smectic into a vortex glass phase.
