This project is a collaboration with the Max Planck Institute for Chemical Physics of Solids in Dresden under the Max Planck partner group scheme. The project focuses on a theoretical study of spintronics phenomena in antiferromagnets and other materials with complex magnetic orders. The main goal is obtaining a fundamental understanding of the transport properties of these materials and finding efficient methods for electrical manipulation and detection of complex magnetic orders. We also explore the role that topology plays in spintronics of complex magnetic structures. The work is done in close collaboration with experimentalists.
