    • Our results are somewhat different from that of et al. (Ref.) who report the preparation of single crystals at 975°C (i.e., above the decomposition temperature of 900°C observed in our experiments). The origin of this discrepancy is not yet clear. We should emphasize that et al. (Ref.) report the preparation of small single crystals only. No information about the synthesis and thermal properties of bulk samples of BaCdVO (PO4) 2 is available.

    • The standard deviations for the exchange integrals originate from the fitting procedure only. Varying the lower limit of the data used, one finds a more pronounced change of J 's, and the actual error bar is of the order of 0.1 K.
