Ultrafast magnetization dynamics and spin transport in magnetic oxide heterostructures (A09)

我们调查的超快自旋相关的载流子动力学和自旋输运过程中的异质结构的磁性氧化物，主要是铁磁绝缘体EuO，结合几个互补的超快技术可在CRC。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，研究了分子束外延生长在各种衬底上的EuO薄膜，以了解这种异质结构中的自旋相关散射过程和输运现象。

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.
