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.

该项目的重点是研究磁性离子与掺杂锰和稀土离子的半导体纳米结构中导带和价带载流子之间的自旋相互作用。理解的关键因素，特别是，交换相互作用是它们的缩放与外部场和磁性离子和载体的浓度。我们将研究二维载气对磁性离子自旋与集体自旋现象（如拓扑霍尔效应和近藤效应）的影响。这些研究将通过调查自旋相互作用，光致磁极化子，在本征磁性铕硫属化物。
