In present work the influence of the disorientation angle between the direction of constant field up to 15 kOe and the ab-plane a º Ð(H,ab) to the temperature dependence of the excess conductivity in the temperature interval of the transition to the superconducting state in untwinned YBa2Cu3O7-d single crystals with a small oxygen hypostoichiometry are investigated. Causes of low-temperature "tails" (parakogerentnyh transitions) in the resistive transitions in superconducting state are analyzed in the framework of the implementation of the various regimes of the phase state of vortex matter.
