Abstract

Single phase samples of the monoclinic and orthorhombic polymorphs of Nb12O29 have been identified and isolated. These polymorphs have different arrangements of nanometer dimension structural columns of ReO3-type niobium oxygen arrays: They differ in structure after a 3-nm translation in one of three dimensions while being the same in the other two. Magnetic susceptibility measurements show that one polymorph displays an antiferromagnetic transition at 12K, along with short-range order fluctuations up to 25K, while the other shows strict Curie-Weiss behavior down to 2K.
