Structural Dataset for NaMnSb Monolayer and Bilayer Stacking Configurations

This dataset provides the principal atomic structures used in the study of spin-symmetry-induced altermagnetism in centrosymmetric square-lattice antiferromagnetic NaMnSb systems. The dataset contains five structural models: a NaMnSb monolayer and AA-, AB-, AC-, and AC'-stacked NaMnSb bilayers. Each model is provided in VASP POSCAR-compatible (.vasp) and CIF (.cif) formats. The structural files specify lattice vectors and atomic coordinates but do not fully encode magnetic moments or distinguish the L1 and L2 spin arrangements. The definitions of L1 and L2 should be taken from the associated manuscript and its Supplemental Material. This dataset contains the five principal structural models listed above. It does not include every intermediate configuration along each sliding path or all VASP input/output files.
