The Emmy Noether Research Group Masell develops theoretical and computational methods to understand, predict and control complex magnetic textures. Our central focus is magnetism in three spatial dimensions, where topological structures such as skyrmion strings, hopfions and magnetic defects exhibit properties that have no direct counterpart in two-dimensional systems.

We combine analytical theory, large-scale micromagnetic simulations, and close collaboration with experimental groups to investigate how these structures form, move and interact. Beyond three-dimensional magnetism, we explore unconventional magnetic order—including altermagnets and odd-parity magnets—and its consequences for domain walls, spin transport and magnetization dynamics.
