提出了一种新型的铁电极化磁起源。在具有三斜、单斜或三角（菱面体）对称性的晶体中，适当的螺旋类型的磁或定义可以通过自旋轨道耦合的金属-配体杂化的变化来诱导铁电性。该机理成功地解释了铜铁矿化合物Cu(Fe,Al)O-2 中的铁电极化。关系
A novel type of magnetic origin of ferroelectric polarization is proposed. In crystals with triclinic, monoclinic, or trigonal (rhombohedral) symmetries, the proper screw type of magnetic ordefing can induce ferroelectricity through the variation in the metal-ligand hybridization with spin-orbit coupling. The ferroelectric polarization in delafossite compounds Cu(Fe,Al)O-2 is successfully explained by the mechanism. The relation
