Предметные рубрики: MUON-SPIN-ROTATION QUASI-PARTICLES FERMI-SURFACE Аннотация: A scenario of the formation of an experimentally observed inflection point on the temperature dependence of the London penetration depth λ in cuprate high-temperature superconductors (HTSCs) with optimal hole doping is discussed within the spin-polaron concept. It is shown that the reason for the appearance of an inflection point on the 1/λ2(T) dependence is due to the features of the energy spectrum of spin-polaron quasiparticles in the superconducting phase, as well as to the specific temperature dependence of their spectral density.
