The thermal-and disorder-induced effects in the mixed state of a layered high-T c
superconductor (in a field H‖ c) are studied. The flux line lattice is of a quasi-2D type at …

The effect of thermal fluctuations on collective flux-pinning and creeps is investigated for thin-
film superconductors and layered superconductors with weak Josephson coupling between …

The theory of collective pinning in the presence of thermal fluctuations of vortex lines is
developed. Critical current jc is shown to decrease rapidly with temperature. Flux creep …

In high-Tc superconductors (HTSC) the thermal fluctuation of the vortex lattice (VL) may
become large since the vortex lattice is soft due to the strong overlap of the vortex fields and …

Magnetic flux can penetrate a type-II superconductor in the form of Abrikosov vortices (also
called flux lines, flux tubes, or fluxons) each carrying a quantum of magnetic flux phi 0= h/2e …

Thermal fluctuations of vortex lines are shown to be capable of strongly reducing the value
of the critical current in the mixed state of high-T c superconductors. The theory of pinning in …

Reversible flux penetration in uniaxial layered superconductors is studied, taking into
account the possible trapping of vortex cores between layers. This is found to induce high …

We investigate the order-disorder transition line from a Bragg glass to an amorphous vortex
glass in the H− T phase diagram of three-dimensional type-II superconductors taking into …

The theory of pinning of a vortex liquid by weak disorder is developed. Two different vortex-
liquid dissipative regimes are shown to exist: the flux flow above some crossover …

Material defects in hard type II superconductors pin the flux lines and thus establish the
dissipation-free current transport in the presence of a finite magnetic field. Depending on the …
