Theoretical investigation of magnetic order in crystals with space group I41md — •Maurice Colling1 and Jan Masell1,21Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany — 2RIKEN CEMS, Wako, Japan

Non-collinear magnetic textures with short ranged modulation in the magnetization exhibit novel transport behavior. Such textures have been proposed to be useful in next generation magnetic memory devices. [1] Materials in the space group I41md (#109), such as the Weyl semimetal GdAlSi, are interesting candidates for investigations in this direction because of the many potentially competing interactions. Long-ranged RKKY interaction might stabilize atomic scale spin spirals. Broken inversion symmetry generates an interfacial Dzyaloshinskii-Moriya interaction which favors Néel type spirals. Dipolar interactions, in turn, favor Bloch type helices. We derive a phenomenological Hamiltonian based on symmetry analysis and present the rich phase diagram.
