Лондоновская глубина проникновения в ансамбле спин-поляронных квазичастиц купратных сверхпроводников

Abstract

In the work on the example of calculation London penetration depth λL is shown that the spin-polaron approach can successfully describe the electrodynamic properties of high temperature cuprate superconductors. To study concentration and temperature dependences of λL was developed a method of calculating the response of an ensemble of spinpolaron of quasiparticles in a uniform field the vector potential Aq=0. Discusses the nature of the calculated concentration and temperature dependences of λL.
