It might be possible that in high temperature layered antiferromagnetic supeconductors an applied magnetic field causes the mixed state to be composed of Josephson vortices possessing magnetic domains. We discuss how this new kind of vortices moves through the intrinsic pinning potential and calculate their activation energy of thermal as well as quantum excitation. We show a possible new phenomenon of crossover from quantum to thermal creep in constant temperature forced by the change of intensity of the external field, or by the change of its direction in the basal plane of layered structure.

The Landau quantization effects are considered in low carrier concentration unconventional spin triplet p-wave superconductors in a high magnetic field region. The field dependence of the superconducting order parameter and the vortex lattice states for intra Landau level pairing are analyzed. The gap functions are calculated within mean field approximation.

It is shown that, independently on either the nature and the strength of pairing, the orbital effects of a high magnetic field in heavy fermion superconductor change the form of both the effective pairing and the gap function.

Electronic structure of a crystal within the tight binding model is described in terms of fibre bundle formalism, with the base and fiber being respectively the set of all sites and the single-centre space of electron spinorbitals. It is based on the Weyl's duality between the symmetric group and the unitary group, and paves the way for a Racah-Wigner type of description of electronic structure in multicentre systems.

Tunneling Current into the Vortex Lattice States of s- and p-Wave Superconductors

The tunneling current between the metallic tip of a scanning microscope and s-wave and p-wave superconductors in a quantizing magnetic field is investigated. The differential conductance is calculated both as a function of bias voltage at the centre of the vortex line and for varying position of the scanning tunneling microscope tip at a stable voltage.

A comparative study of structural and superconductive properties of semi conductor epitaxial superlattices PbTe-SnTe and PbTe-PbS grown on (001) KCl has been carried out. It has been found that the superconductivity of the PbTe-SnTe superlattices is caused by the stretching strain in the SnTe layers and it may be connected with the relative positions of L^{+}_{8} and L^{+}_{6} terms of PbTe and SnTe, respectively in the heterojunction. In contrast to the PbTe-SnTe superlattices, the superconductivity of the PbTe-PbS super lattices is found to be associated with regular misfit dislocation grids which are generated at the interfaces.
