Investigation of anisotropy influence upon some properties of crystalline high-temperature superconductors

Subject of inquiry is superconductors with anisotropic opder parameter.The aim of the work is the development of a theoretical model energy gap for interpretation of experimental data on high-temperature superconductors, taking into account anisotropy. The work covers new types of peculiarities of quasi-particle state density in anisotropic superconductor, temperature dependence, heat capacity, nuclear spin and acoustic damping relaxation volt-ampere characteristic, point contacts, acoustic absoprtion frequency responce under low temperatures and near phase transition. Intepretation of substantial amount of experimental data on high-temperature superconductors has been offered. Explanations on the basis of unified approach connected with order parameter anisotropy have been givenAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
