Double perovskites exhibit frustration in the presence of antiferromagnetic correlations, and the nature of magnetic interactions may be determined by fitting the susceptibility data. In our measurements, all five compounds exhibited Curie-Weiss behavior with large and negative Curie-Weiss temperatures indicative of antiferromagnetic correlations. No evidence of magnetic order was found to 2K, indicating high frustration indices as seen in spin-singlet candidates such as Ba2YMoO6 and Ba2LuMoO6.
