Statistical Models of the Polaronic Phase Transition in Manganites
We propose two statistical models for description the metal-insulator phase transition coupled with paramagnetic-ferromagnetic phase transition in manganites of the type La_{1-x}Sr_xMnO_3. The first one based on the competition of small polarons and delocalized carriers. In the second one the conduc...

| description | We propose two statistical models for description the metal-insulator phase
transition coupled with paramagnetic-ferromagnetic phase transition in
manganites of the type La_{1-x}Sr_xMnO_3. The first one based on the
competition of small polarons and delocalized carriers. In the second one the
conductivity appears as a result of overlapping of large polarons. We compare
our models with the experimental data. |
