Abstract Binary () and ternary () ferroelectrics-magnetics with the perovskite structure, containing the 3d-metal atoms, are investigated. Some correlations between their ferro- or antiferroelectric (TC) and magnetic (TN) phase transition temperatures and their interatomic A-O (), and B-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 TC-TN difference was revealed. Such correlations can help with the search for new solid solution systems between different ferroelectrics-magnets with enough high TC and TN and low TC-TN difference with using of apriori determined and values.

具有钙钛矿结构的铁电磁性

摘要 研究了含有 3d 金属原子的钙钛矿结构的二元 ( ) 和三元 ( ) 铁电磁性材料。使用准弹性结构模型确定了它们的铁或反铁电 (TC) 和磁性 (TN) 相变温度与其原子间 AO () 和 BO () 键应变之间的一些相关性。揭示了后者的结构参数和相变温度本身对其 TC-TN 差异的影响。这种相关性可以帮助在具有足够高的 TC 和 TN 以及低 TC-TN 差异的不同铁电磁铁之间寻找新的固溶体系统，并使用先验确定的值。
