a Cr L3,2 edge in MnCr2O4 and A5Cr2O4. b Mn L3,2 edge in MnCr2O4 and A5Cr2O4. c Co L3,2 edge in CoCr2O4 and A5Cr2O4. d Ni L3,2 edge in NiCr2O4 and A5Cr2O4. e Cu L3,2 edge in CuCr2O4 and A5Cr2O4. The spectra of Cr and Mn for MnCr2O4 is taken from ref. 51. The spectra of Co for CoCr2O4 is adapted from ref. 75. f Spin configurations of Cr, Mn, Co, Ni, Cu, and Zn cations in A5Cr2O4. The energy gap between t2g (t2) and eg (e) is not according to the scale.
