Critical current in type-II superconductors near the order-disorder transition
We investigate theoretically the critical states in a long thin superconducting strip with a critical transport current and in a perpendicular magnetic field, which is close to the field of the order-disorder transition in the vortex lattice. In this investigation, the metastable disordered states and the self-magnetic-field of the current are taken into account. Using the obtained results, the dependence of the dc critical current in the strip on the applied magnetic field is found near the order-disorder transition. This dependence can be used to describe the peak effect in low- superconductors and the second magnetization peak in high- superconductors, which occur near this transition.- 22 February 2010

Transport properties of vortex matter governed by the edge inductance in superconductingcrystalsWe study the distribution of transport current across superconducting crystals and the vortex flow through the sample edges. We show that the transition is of electrodynamic rather than thermodynamic nature, below which vortex dynamics is governed by the edge inductance instead of the resistance. This allows measurement of the resistance down to 2 orders of magnitude below the transport noise. By irradiating the current contacts the resistive step at vortex melting is shown to be due to loss of -axis correlations rather than breakdown of quasilong-range order within the planes.- 31 December 2009

Nanomechanics of an individual vortex in an anisotropic type-II superconductor
As shown in recent experiments [Auslaender et al., Nat. Phys. 5, 35 (2009)] magnetic force microscopy permits one not only to image but also to manipulate an individual vortex in type-II superconductors, and this manipulation provides a new powerful tool to study vortex dynamics and pinning. We derive equations that describe the deformation of an individual vortex in an anisotropic biaxial type-II superconductor under the action of the microscope’s magnetic tip. These equations take into account the driving force generated by the tip, the elastic force caused by the vortex deformation, and the pinning force exerted by point defects. Using these equations, we reproduce the main features of the experimental data obtained by Auslaender et al.

Longitudinal magnetic field increases critical current in superconducting strip
The critical state of the vortex lattice in a thin strip is considered for the case when first a perpendicular magnetic field is applied, then a longitudinal field, and then again the perpendicular field is increased. This longitudinal field can strongly enhance the critical currents in the strip since the vortices are inclined and the currents flow in the strip plane.
