Paper Abstract

An oscillating electron model for iron of selenide FeSe, niobium of germanate Nb3Ge, magnesium diboride MgB2, cuprate YBa2Cu3O6.5+χ, mercury cuprate HgBa2Ca2Cu3O8+ χ superconductors was considered. The superconducting phase transition is accompanied by the destruction of valence bonds, phase separation and the formation of molecules takes place. For the case of a binary crystal, this process can be represented in the form 2AB = A2 + B2. The square plasma energies ħωpv 2 and the interaction parameters q = 2ω2 [ab] / (ω2 [a2] + ω2 [b2]) were calculated. The dependence of the superconducting phase transition temperature Tc on the interaction parameter q was obtained. The equation has the form Tc = ─ 188.66537q + 181.40836. Equations for the isotope effect of iron selenide FeSe, magnesium diboride MgB2, cuprate YBa2Cu3O6.5 + χ have been obtained.
