Magneto-electro-optical Interaction and their dynamics of oxide heterostructures (B03)

目的是开发一种剩余可切换光波导，其中铁电，铁磁或多铁性材料的可切换磁化或电极化场用于切换谐振或传播光模式的特性作为信号。为此，我们将主要研究(1)磁性尖晶石和多铁BaTiO3/ bifeo3复合材料的基本光学和磁光性质；(2)所述场对相邻电介质或半导体器件光学特性的影响；(3)它们在fs- ms时间范围内切换的动力学。

Aim is to develop a remanently switchable optical waveguide, in which the switchable magnetisation or elec-tric polarization fields of a ferroelectric, ferromagnetic, or multiferroic material is used to switch the proper-ties of resonant or propagating optical modes as a signal. To this end we will investigate (1) basic optical and magneto-optical properties of, primarily, magnetic spinels and multiferroic BaTiO3/BiFeO3-composites; (2) the influence of the mentioned fields on the optical properties of an adjacent dielectric or semiconduc-tor; (3) the dynamics of their switching in the fs- to ms-time-range.
