a Fitting of inverse magnetic dc susceptibility using Curie-Weiss equation above TN in A5Cr2O4 at 5000 Oe. Inset features field cooled (FC) dc susceptibility as a function of temperature. b The Curie-Weiss temperature -θCW is plotted as a function of Cr-Cr bond distance and A-site spin. c -θCW is plotted as a function of Cr-O bond distance and A-site spin. Both plots include data for the parent oxides and the A5Cr2O4. The error bars represent the standard error of the mean in each bond distance. d A comparison of the magnetic exchange interaction energy between two Cr cations (JCrCr), between Cr and A (JACr), and between two A cations (JAA) in MnCr2O4 and A5Cr2O4.
