WebJul 6, 2016 · In section 3, we first show the orbital-selective Mott transition (OSMT) introduced by the Hund's rule coupling in undoped compound. Then we study the cooperative effect of the Hund's rule coupling and impurity-induced disorder on the phase transitions in Cu-substituted iron-based superconductors. WebJun 29, 2024 · Another example of competing interactions is the orbital-selective Mott phase (OSMP) (22, 23). In multiorbital systems, this effect can lead to the selective localization of electrons on some orbitals. The latter coexist with itinerant bands of mobile electrons. This unique mixture of localized and itinerant components in multiorbital …
