Abstract Multiferroic materials have attracted a remarkable interest due to its high potential for magneto-electrical coupling; however, the knowledge about magneto-optical coupling remains incipient. Some particular works have focused on the dependency between optical and magnetic properties through the two types of Kerr effects in this kind of material. In this work, we have investigated the optical and magneto-optical Kerr effects on PbNiO3, PbCrO3, and PbMnO3 through an excited-state approach. Our calculations have predicted the Kerr effect from the refractive index tailoring as a function of the ground and excited states. In this context, the magneto-optical Kerr effect increased the magnetization along excited state allied to the magneto-crystalline anisotropy observed for R3c materials. Furthermore, we propose a molecular origin for the two kinds of Kerr effects.

PbNiO3、PbCrO3 和 PbMnO3 多铁性材料中的磁光耦合和克尔效应：一种激发态方法

摘要 多铁性材料因其在磁电耦合方面的巨大潜力而​​引起了人们极大的兴趣。然而，有关磁光耦合的知识仍处于起步阶段。一些特别的工作通过这种材料中的两种类型的克尔效应专注于光学和磁性之间的依赖性。在这项工作中，我们通过激发态方法研究了 PbNiO3、PbCrO3 和 PbMnO3 的光学和磁光克尔效应。我们的计算已经根据作为基态和激发态的函数的折射率剪裁预测了克尔效应。在这种情况下，磁光克尔效应增加了沿激发态的磁化强度，这与 R3c 材料观察到的磁晶各向异性有关。此外，
