我们报告了一个显着的增强的磁矩的激子作为一个结果，他们的运动。这一令人惊讶的结果，我们已经观察到在磁光研究的三个不同的锌-碲化锌半导体，GaAs，CdTe，和ZnSe，变得显着的激子的动能变得与它的里德伯能量相当，并归因于运动引起的变化的激子的内部结构。磁矩的增强作为激子平移波矢的函数可以由一个普适方程表示。
We report a remarkable enhancement of the magnetic moments of excitons as a result of their motion. This surprising result, which we have observed in magneto-optical studies of three distinct zinc-blende semiconductors, GaAs, CdTe, and ZnSe, becomes significant as the kinetic energy of the exciton becomes comparable with its Rydberg energy and is attributed to motionally induced changes in the internal structure of the exciton. The enhancement of the magnetic moment as a function of the exciton translational wave vector can be represented by a universal equation.
