Spin interactions between magnetic ions and carriers (B04)

该项目的重点是研究同时掺杂锰和稀土离子的半导体纳米结构中磁性离子与导带和价带载流子之间的自旋相互作用。尤其是，了解交换作用的关键因素是它们与外场的比例以及磁性离子和载流子的浓度。我们将研究二维载流子气体对集体自旋现象如拓扑霍尔效应和近藤效应的影响。这些研究将通过研究光诱导的磁极化子的自旋相互作用来完善这些研究，这些自旋相互作用仅仅是在本质上具有磁性的硫属铕中的。

The project focuses on studying spin interactions between magnetic ions and conduction-band and valence-band carriers in semiconductor nanostructures doped with both Manganese as well as rare-earth ions. The key factor for understanding the, in particular, exchange interactions is their scaling with external fields and the concentrations of the magnetic ions and carriers. The impact of two-dimensional carrier gases on the magnetic ion spins with respect to collective spin phenomena like the topological Hall and Kondo effect will be studied. These studies will be rounded off by investigating spin interactions, merely of photo-induced magnetic polarons, in intrinsically magnetic Europium chalcogenides.
