By examining the excitation spectra of both type-II superconductors with BCS like interaction and local-pair superconductors with negative-U type interaction, it is concluded that gapless single particle energy spectrum is a characteristic feature of superconductivity in very high magnetic fields.EnglishElectronsMagnetic fieldsMathematical modelsPhononsSpectrum analysisSuperconducting materialsElectromagnetic propertiesNarrow band systemsSuperconductivityArticle1303-6122
