HALL-EFFECT IN LAYERED SUPERCONDUCTORS AT TILTED MAGNETIC-FIELD

In the frameworks of two models -- <<rigid>> vortices with a stepped c onfiguration (a kink-string model) and three-dimensional anisotropic m edium (a scaling model) the angular dependences of resistivity tensor components are calculated for layered superconductors at tilted magnet ic field with taking into account the percolative character of their m ovement in a medium with a nonuniform pinning. The comparison of the n umerical calculations with the experimental investigations of the Hall resistivity angular dependences in YBa2Cu3O7 single crystals at T app roximate to 84 K and tilted magnetic field up to 10 T favours the vali dity of the first model.
