Two Ferromagnetic Phases in Spin-Fermion Systems
Naoum Karchev
We consider spin-fermion systems which get their magnetic properties from a system of localized magnetic moments being coupled to conducting electrons. The dynamical degrees of fre…

Curie temperature of the two band double exchange model for manganites
Vasil Michev, Naoum Karchev
We consider two-band double exchange model and calculate the critical temperature in ferromagnetic regime (Curie temperature). The localized spins are represented in terms of the S…
