Comment on the second-order phase transition in FeCr2S4

It is demonstrated, mainly on the basis of symmetry arguments, that an interpretation of the 13 K phase transition in Fe${\mathrm{Cr}}_2$ ${\mathrm{S}}_4$ in terms of hybridization of $3d^6$ ${\mathrm{Fe}}^{2+}$ electronic states with excited ${\mathrm{Cr}}^{2+}$ states is in conflict with experimental evidence.
