We investigate the ultrafast spin-dependent carrier dynamics and spin-transport processes in heterostructures of magnetic oxides, primarily the ferromagnetic insulator EuO, combining several complementary ultrafast techniques available within the CRC. Thin films of EuO grown by molecular beam epitaxy on various substrates will be investigated by femtosecond time-resolved photoelectron spectroscopy, X-ray magnetic circular dichroism, THz spectroscopy and magneto-optics to understand the spin-dependent scattering processes and transport phenomena in such heterostructures.

我们研究了磁氧化物异质结构的超快自旋依赖性载体动力学和自旋传输过程，主要是铁磁绝缘子EUO，结合了CRC中可用的几种补充超级快速技术。通过分子束外延生长的各种底物上的EUO的薄膜将通过飞秒时间分辨的光电光谱，X射线磁性圆形二色性，THZ光谱和磁磁镜来研究，以了解此类杂种构造中的自旋依赖散射过程和转运现象。
