It was illustrated that in the absence of external magnetic field, the two-band model reduced to a single effective band theory with modified temperature dependences. The calculations revealed three-dimensional character of fluctuations of conductivity in the new Fe-based superconductor SmFeAsO0.8F0.2. It has been shown that such a model is in good agreement with experimental data for this compound.eninfo:eu-repo/semantics/openAccessfluctuationconductivityGinzburg-Landau theorytwo-band superconductivityArticle10.1515/msp-2015-00602-s2.0-849459425066483N/A64433WOS:000370254500015Q4
