摘要: Using 1+1 soliton-like polaron model of a deformable continuum, the critical temperature and the energy gap in high-temperature superconductors Y1-xCaxBa2Cu3-xMxO7-δ(M=Fe,Ni) are studied in the framework of finite temperature Green's function theory. The ratio 2Δ/kBTc=3.9 is obtained. Theoretical results are found in good agreement with the experimental data.
