Description
The asymmetric exchange interaction, discovered by Dzyaloshinsky and Moriya at mid of the last century, has long been known in bulk systems, e.g., in context to weak ferromagnetism. Only recently, the rapidly developing research of magnetic nanostructures revealed many novel and challenging consequences of the DM interactions, such as the homochirality of domain walls, the chiral asymmetry of spin-waves, the formation of long range magnetic patterns and skyrmion states in ultrathin films, as well as the exchange bias at spin-flop coupled antiferromagnet-ferromagnet interfaces. In particular, it will be demonstrated how first principles calculations help to explore this emerging field of nanomagnetism.
