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.

我们研究了磁性氧化物（主要是铁磁绝缘体 EuO2）异质结构中的超快自旋相关载流子动力学和自旋输运过程，结合了 CRC 中可用的几种互补超快技术。通过飞秒时间分辨光电子能谱、X射线磁圆二色性、太赫兹光谱和磁光技术研究在各种基底上通过分子束外延生长的EuO薄膜，以了解此类异质结构中的自旋相关散射过程和输运现象。
