Origin of the enhanced magnetic ordering temperature in CoV2O4. Projected density-of-states of CoV2O4 (a) compared to MnV2O4 (b) in unit of eV−1. Dotted arrows denote the energy differences, Δ between V and Co/Mn for possible AFM super-exchange (J A−V ~ −t 2/Δ). t is the hopping parameter between orbitals.
