Quasiclassical Approach to the Vortex State in Iron-based Superconductors

The quasiclassical approach was applied to the investigation of the vortex properties in the ironbased superconductors. The special attention was paid to manifestation of the nonlocal effects of the vortex core structure. The main results are as follows: (i) The effects of the pairing symmetries (s+ and s₊₊) on the cutoff parameter of field distribution, ξh, in stoichiometric (like LiFeAs) and nonstoichiometric (like doped BaFe₂As₂) iron pnictides have been investigated using Eilenberger quasiclassical equations. Magnetic field, temperature and impurity scattering dependences of ξh have been calculated. Two opposite behavior have been discovered. The ξh /ξc2 ratio is less in s+ symmetry when intraband impurity scattering (Γ₀) is much larger than one and much larger than interband impurity scattering (Γπ), i.e. in nonstoichiometric iron pnictides. Opposite, the value ξh /ξc2 is higher in s+ case and the field dependent curve is shifted upward from the "clean" case (Γ₀ = Γπ = 0) for stoichiometric iron pnictides (Γ₀ = Γπ ≪ 1). (ii) Eilenberger approach to the cutoff parameter, ξh, of the field distribution in the mixed state of high

Introdução à família Tarsonemidae Kramer, 1877 (Acarina) no estado de São Paulo

No presente trabalho é dada uma introdução à família Tarsonemidae e são relatadas as seguintes espécies: Polyphagotarsus latus (Banks, 1904) Beer & Nucifora, 1965; Tarsonemus setifer Ewing, 1939; Steneotarsonemus ananas (Tryon, 1898) Beer, 1954; S. pallidus (Banks, 1901) Beer, 1954; S. hyaleos Beer, 1954 e Rhynohotarsonemus sp. Uma chave para a separação dos gêneros e outra para a separação das espécies de Steneotarsonemus é apresentada.
