Direct Evidence for Edge-Contaminated Vortex Phase in a Nb Single Crystal using Neutron Diffraction
Helen A. Hanson, Xi Wang, Ivo K. Dimitrov +7
We report the first direct observation of a disordered vortex matter phase existing near the edge of a bulk type-II superconductor Nb using a novel position-sensitive neutron diffr…
The Absence of Vortex Lattice Melting in a Conventional Superconductor
C. J. Bowell, R. J. Lycett, M. Laver +3
The state of the vortex lattice extremely close to the superconducting to normal transition in an applied magnetic field is investigated in high purity niobium. We observe that the…
Morphology of the Superconducting Vortex Lattice in Ultra-Pure Niobium
S. Mühlbauer, C. Pfleiderer, P. Böni +5
The morphology of the superconducting flux line lattice (FLL) of Nb comprises gradual variations with various lock-in transitions and symmetry breaking rotations. We report a compr…
Fermi surface and order parameter driven vortex lattice structure transitions in twin-free YBa2Cu3O7
J. S. White, V. Hinkov, R. W. Heslop +12
We report on small-angle neutron scattering studies of the intrinsic vortex lattice (VL) structure in detwinned YBa2Cu3O7 at 2 K, and in fields up to 10.8 T. Because of the suppres…
