Phase diagrams of $\mathrm{L}{\mathrm{a}}_{1-\mathrm{x}}\mathrm{C}{\mathrm{a}}_{\mathrm{x}}\mathrm{Mn}{\mathrm{O}}_3$ in Double Exchange Model with added antiferromagnetic and Jahn-Teller interaction

Vasil Michev, Naoum Karchev

The phase diagram of the multivalent manganites $\mathrm{L}{\mathrm{a}}_{1-\mathrm{x}}\mathrm{C}{\mathrm{a}}_{\mathrm{x}}\mathrm{Mn}{\mathrm{O}}_3$, in space of temperature and doping $x$, is a challenge for the theoretical physics. It is an important test…
