Abstract: ABSTRACT ( is a room‐temperature magnet with symmetry that hosts a rich variety of topological spin textures. Here, we report a combined resonant small‐angle x‐ray scattering and ptychography study of ( in vector magnetic fields over a broad temperature range. We demonstrate deterministic vector‐field control of magnetic stripe domains, where in‐plane fields continuously rotate their orientation via a transition from a chiral stripe to an achiral fan configuration. Furthermore, at 50 K and below, the stripe orientation becomes metastably pinned and retains its field‐trained direction. While the magnitude of the wavevector is nearly isotropic within the basal plane at room temperature, a pronounced temperature evolution of anisotropic interactions emerges upon cooling. In particular, non‐trivial anisotropy axes develop at 20–50 K reflecting the combined effects of magnetocrystalline anisotropy, anisotropic exchange, and Dzyaloshinskii–Moriya interaction (DMI), whose effective orientation is found to rotate with temperature. These results establish ( as a model system for vector‐field control of chiral spin textures and reveal a previously unrecognized temperature‐driven evolution of the effective DMI landscape in a noncentrosymmetric magnet.
