Spin interactions between magnetic ions and carriers (B04)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2015 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 249492093

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.
