- Abstract
- The phase diagram of the doped perovskite manganites is obtained with the Hamiltonian that includes the degenerate orbital double exchange interaction and the antiferromagnetic (AF) Heisenberg interaction. The ground state and the finite temperature phase diagram with varying t/J and doping level have been obtained. Our results such as G-->C-->A-->F-type magnetic transition with electron doping, T-N minimum at the C-->A-AF transition, and the A-AF to ferromagnetic transition upon heating are consistent with the experimental observation.
