Effect of Jahn-Teller coupling on Curie temperature in the Double Exchange Model
Vasil Michev, Naoum Karchev
We consider the two-band double exchange model for manganites with Jahn-Teller (JT) coupling and explore the suppression of the ferromagnetism because of the JT distortion. The loc…

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…

Canted Ferromagnetism in Double Exchange Model with on-site Coulomb Repulsion
Naoum Karchev, Vasil Michev
The double exchange model with on-site Coulomb repulsion is considered. Schwinger-bosons representation of the localized spins is used and two spin-singlet Fermion operators are in…
