Influence of exchange fields in hybrid pairing superconductors II. Selfconsistent ground states

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

A previously investigated model of a two band superconductor with hybrid pairing and molecular fields is enlarged by exchange interactions generating those fields. The fields are calculated selfconsistently in molecular field approximation at zero temperature. They turn out to stabilise the previously found new state of gapless superconductivity and non vanishing spin polarization for a wide range of exchange couplings, in particular for zero external field.
