Ferroelectrics-magnetics with the perovskite structure

Abstract

Binary ($A^{\text{III}}{B}^{\text{III}}{\mathrm{O}}_3$) and ternary ($A^{\text{II}}{B}_{{\beta }_1}^1{B}_{{\beta }_2}^2{O}_3$) ferroelectrics-magnetics with the perovskite structure, containing the 3d-metal atoms, are investigated. Some correlations between their ferro- or antiferroelectric (T _C) and magnetic (T _N) phase transition temperatures and their interatomic A-O (${\delta }_{A\mathrm{O}}$), and B-O (${\delta }_{B\mathrm{O}}$) bonds strains, determined with using of quasi-elastic structure model, have been constructed. The latter structural parameters and phase transition temperatures themselves influence on their T _C-T _N difference was revealed. Such correlations can help with the search for new solid solution systems between different ferroelectrics-magnets with enough high T _C and T _N and low T _C-T _N difference with using of apriori determined ${\delta }_{A\mathrm{O}}$ and ${\delta }_{B\mathrm{O}}$ values.
