Summary
The magnetic phases that can be formed in chiral magnets has been of increasing interest due to the unique and exciting physics and potential applications these materials have. The chiral magnetism in these materials is created by the competition of energy terms in the Hamiltonian, namely exchange and the Dzyaloshinsky-Moriya Interaction (DMI). This DMI is created from the asymmetric environment of interacting magnetic spins and is thus connected with non-centrosymmetric crystallographic point groups. As these non-centrosymmetric point groups have different symmetries the form of the DMI equation changes from one to the next. However, only a small number of DMI point groups have been studied so far.
This project will investigate the physics of the yet unexplored DMI terms computationally. These terms will be integrated into micromagnetic calculators and will be made open-source to enable the magnetism community to use it for research outside of this project. The multidimensional parameter space of these new DMI terms will be systematically investigated for new magnetic structures using machine learning techniques. Novel magnetic structures discovered will have their stability, equilibrium and non-equilibrium dynamics studied to gain new physics insights. This will lead to exciting new physical phenomena being discovered which may have the potential for applications in spintronics.
