| 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. (AU) | |
