Reversible ordering and disordering of the vortex lattice in UPt3
K. E. Avers, S. J. Kuhn, A. W. D. Leishman +7
When studied by small-angle neutron scattering the vortex lattice (VL) in UPt3 undergoes a gradual disordering as a function of time due to 235U fission. This temporarily heats reg…
Structural studies of metastable and equilibrium vortex lattice domains in MgB2
E. R. Louden, A. W. D. Leishman, C. Rastovski +5
The vortex lattice in MgB2 is characterized by the presence of long-lived metastable states, which arise from cooling or heating across the equilibrium phase boundaries. A return t…
Structural Transition Kinetics and Activated Behavior in the Superconducting Vortex Lattice
E. R. Louden, C. Rastovski, S. J. Kuhn +5
Using small-angle neutron scattering, we investigated the behavior of a metastable vortex lattice state in MgB2 as it is driven towards equilibrium by an AC magnetic field. This sh…
Vortex lattices and broken time reversal symmetry in the topological superconductor UPt3
K. E. Avers, W. J. Gannon, S. J. Kuhn +8
The topological superconductor UPt3, has three distinct vortex phases, a strong indication of its unconventional character. Using small-angle neutron scattering we have probed the…
Anisotropy and multiband superconductivity in Sr2RuO4
S. J. Kuhn, W. Morgenlander, E. R. Louden +8
Despite numerous studies the exact nature of the order parameter in superconducting Sr2RuO4 remains unresolved. We have extended previous small-angle neutron scattering studies of…
Persistent Magnetism in Silver-doped BaFe2As2 Crystals
Li Li, Huibo Cao, David S. Parker +2
We investigate the thermodynamic and transport properties of silver-substituted BaFe2As2 (122) crystals, up to ~4.5%. Similar to other transition-metal substitutions in 122, Ag dim…
