Abstract

A novel Mo⁵⁺ double perovskite, Sr₂ScMoO₆, has been synthesised. This material crystallises in the tetragonal I4/m symmetry space group and considerable cation disorder between Sc³⁺ and Mo⁵⁺ is observed. Magnetic susceptibility measurements show no evidence of a magnetic transition down to 6 K and no evidence of the valence bond glass state previously reported for A₂YMoO₆ (A=Ba, Sr). The inverse susceptibility data cannot be fit to the Curie-Weiss law at any temperature range between 6 and 300 K. This deviation from Curie-Weiss law suggests that strong antiferromagnetic correlations are still present in Sr ₂ScMoO₆.
