Abstract

Different mechanisms of superconductivity result in specific symmetries and structures of the gap in multiband systems. Here we review the spin fluctuation mechanism of Cooper pairing and discuss the spin resonance feature in the superconducting state of iron-based materials.

Keywords

Fe-based superconductors, spin resonance peak, spin fluctuation mechanism of pairing
