Their corresponding spin point groups are the symmetry groups to be considered for deriving the symmetry constraints on the form of the crystal tensor properties of such idealized structures. These groups can also be taken as approximate symmetries (with some restrictions) of real magnetic structures, where spin\u2013orbit coupling and magnetic anisotropy are however present. Here we formalize the invariance transformation properties that must satisfy the most important crystal tensors under a spin point group. This is done using modified Jahn symbols, which generalize those applicable to ordinary magnetic point groups [Gallego\n                    <jats:italic>et al.<\/jats:italic>\n                    (2019).\n                    <jats:italic>Acta Cryst.<\/jats:italic>\n                    A\n                    <jats:bold>75<\/jats:bold>\n                    , 438\u2013447]. The analysis includes not only equilibrium tensors, but also transport, optical and non-linear optical susceptibility tensors. The constraints imposed by spin collinearity and coplanarity within the spin group formalism on a series of representative tensors are discussed and compiled. As illustrative examples, the defined tensor invariance equations have been applied to some known magnetic structures, showing the differences in the symmetry-adapted form of some relevant tensors, when considered under the constraints of its spin point group or its magnetic point group. This comparison, with the spin point group implying additional constraints in the tensor form, can allow one to distinguish those magnetic-related properties that can be solely attributed to spin\u2013orbit coupling from those that are expected even when spin\u2013orbit coupling is negligible.\n                  <\/jats:p>","DOI":"10.1107\/s2053273325004127","type":"journal-article","created":{"date-parts":[[2025,5,22]],"date-time":"2025-05-22T11:21:26Z","timestamp":1747912886000},"page":"317-338","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":9,"title":["Crystal tensor properties of magnetic materials with and without spin\u2013orbit coupling.
