The exploration of magnetic phases in chiral magnets has gathered significant interest due to the unique physics and potential applications of these materials. A key factor in these systems is the Dzyaloshinsky-Moriya interaction (DMI), which arises from the asymmetric environment of interacting magnetic spins and is linked to non-centrosymmetric crystallographic point groups. While a few point groups have had their DMI extensively studied, many remain unexplored.
In this talk, we systematically explore the multidimensional parameter space of these new DMI terms using micromagnetic simulations to identify and classify magnetic phases. Machine learning algorithms, such as clustering and autoencoders, are employed to automate this process, enabling the rapid identification and grouping of similar magnetic phases across extensive parameter spaces.
