Abstract of the dataset | This dataset contains the experimental and simulation data underlying the figures of the corresponding publication, which reports a field-induced crossover from π to 2π chiral soliton lattices in the Heusler compound Mn1.4PtSn. All measurements were performed on the same focused-ion-beam lamella at room temperature, with the magnetic field applied out of plane (along the crystallographic c axis). The data are organized by method: (1) 1_LTEM — Lorentz transmission electron microscopy: transport-of-intensity (TIE) reconstructions of the magnetic phase and in-plane induction on a region of interest as a function of field (Figs 2, 3, 6), the two full-field raw micrographs at 0 and 300 mT shown in Fig 1, and the measured stripe period and domain widths vs field (Fig 3); (2) 2_REXS — resonant elastic X-ray scattering at the Mn L3 edge (Diamond I10): raw detector frames of the 0–550 mT field upsweep (Fig 1) and the extracted propagation-vector magnitude and harmonic intensities vs field (Figs 3, 4), with the analysis notebook; (3) 3_micromagnetics — Mumax3 input scripts and output (magnetization fields, energies, applied field) for the final field sweep that reproduces the measured modulation length, domain widths and harmonic content (Figs 6, 7, 8); (4) 4_model — a phenomenological 1D stripe-domain model (script, generated spin textures and induction profiles) used to deduce and visualize the spin textures (Figs 2g–o, 6); (5) figure_plots — the OriginPro projects holding the plotted data behind Figs 3, 4, 6 and 8. Together these data establish that the magnetic ground state of Mn1.4PtSn is a π-soliton lattice rather than a helical spiral, and that it condenses continuously into a conventional 2π-CSL under increasing out-of-plane field. A top-level README and Fig_to_data_map.csv document the file formats and the mapping between data and figures. | |

Project abstract | Chiral soliton lattices (CSLs) emerge from the competition between Dzyaloshinskii–Moriya interaction, anisotropy, and magnetic fields. While well established in monoaxial helimagnets, their role in materials with anisotropic, direction-dependent chirality remains poorly understood. Here, we report the direct observation of a crossover from π to 2π soliton lattices in the non-centrosymmetric Heusler compound Mn1.4PtSn. Combining Lorentz transmission electron microscopy, resonant elastic X-ray scattering, and micromagnetic simulations, we identify a π-CSL as the magnetic ground state—rather than the expected spiral phase—which evolves into a classical 2π-CSL under increasing out-of-plane fields. This transition is governed by an interplay between uniaxial magnetocrystalline anisotropy and magnetostatic interactions, qualitatively captured by a double sine-Gordon model. Our framework extends to materials with D2d, S4, Cnv, or Cn symmetries in the thin-film limit, providing a unifying route to engineer magnetic phase diagrams in chiral systems with implications for soliton-based spintronics and topological transport. | |
