原始语种摘要: We investigate the stability of multiple- Q spiral states in d – p electron systems with the strong spin–charge coupling. By using variational calculations on a square lattice, we find that the double- Q state with the scalar chirality density wave, which has been studied in the weak spin–charge coupling regime, becomes the ground state even in the strong spin–charge coupling regime by considering the effect of the d – p hybridization. We also show that the regions where the double- Q state is stabilized are widely extended for introducing the antiferromagnetic superexchange interaction between nearest-neighbor localized spins.
