Vortex phases in YBa2Cu3Oy for B vertical bar vertical bar CuO: impact of regular and random pinning

Zhukov, A.A., Filby, E.T., de Groot, P.A.J., Kupfer, H. and Wolf, T. (2004) Vortex phases in YBa2Cu3Oy for B vertical bar vertical bar CuO: impact of regular and random pinning Physica C: Superconductivity And its Applications, 408-410, pp. 541-542. (doi:10.1016/j.physc.2004.03.205).

Record type: Article


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.
