Phase diagrams of $L a_{1 - x} C a_{x} Mn O_{3}$ in Double Exchange Model with added antiferromagnetic and Jahn-Teller interaction

Vasil Michev, Naoum Karchev

The phase diagram of the multivalent manganites $L a_{1 - x} C a_{x} Mn O_{3}$ , in space of temperature and doping $x$ , is a challenge for the theoretical physics. It is an important test…

Ferromagnetic phases in spin-Fermion systems

N. Karchev

Spin-Fermion systems which obtain their magnetic properties from a system of localized magnetic moments being coupled to conducting electrons are considered. The dynamical degrees…
