ANALYTICAL PROPERTIES OF MUON POLARIZATION SPECTRA IN TYPE-II SUPERCONDUCTORS AND EXPERIMENTAL-DATA INTERPRETATION FOR MONOCRYSTALLINE AND POLYCRYSTALLINE HTSCS

The authors have solved Ginzburg-Landau equations for an intermediate magnetic field for type-II superconductors. The solution was obtained from the solution for a strong magnetic field via simple transformation. Hence, a set of results obtained at the case of the strong magnetic field is applicable to that of the intermediate field which is much easier to get experimentally and more informative. The authors analyzed properties of muon polarization spectra in mono- and polycrystalline HTSCs at the intermediate magnetic field. On the basis of analytical properties the authors suggested the way to interpret mu-SR experimental data.
