a Top and b side view of the unit cell of CeNiAsO crystal and the co-planar magnetic order with \({{{\mathcal{T}}}}t\) symmetry. The out-of-plane spin projected constant energy isosurface at E ~ −0.1 eV c and E ~ 0.12 eV d in the kz = 0 momentum plane. e Nonrelativistic odd-parity wave spin splitting of energy bands plotted along the − X-Γ-X path. The colormap represents the out-of-plane 〈Sz〉 component. f The symmetry-allowed components of non-equilibrium intra-band susceptibility density, \({\chi }_{S}^{zx}\) and \({\chi }_{S}^{zz}\). The modifications of the specific components in the presence of SOC are shown in dashed curves. The isoenergy cuts of (c) and (d) are at the energy where the \({\chi }_{S}^{zx}\) component of the NREE susceptibility acquires maximum and minimum values, as indicated by dotted lines in f. g Susceptibility components arise due to the sole relativistic effect. SOC leads to finite \({\chi }_{S}^{xx}\), \({\chi }_{S}^{xz}\) and \({\chi }_{S}^{yy}\) which are not allowed within the NREE susceptibility tensor.
