| The influence of electric field on the structure parameters and magnetic states in BiFeO3 multiferroic is studied using the Landau theory of phase transitions taking into account experimental data and results of ab initio calculations. Main features of structure transitions near critical electric fields and a concomitant rearrangement, of the magnetic structure are discussed. |
