Abstract: | We use a simplified model to calculate the electronic band structure of compounds of the type of La1?xSrxMnO3. The model includes two nonequivalent sites for the transition metal ions as well as strong Coulomb and exchange interactions between d electrons. Using the resulting band structure we discuss the correlation between magnetic order and conductivity in these compounds. |
