Nanocrystalline Antiferromagnetic High-κ Dielectric Sr₂NiMO₆ (M = Te, W) with Double Perovskite Structure Type.

ABSTRACT: Double perovskites have been extensively studied in materials chemistry due to their excellent properties and novel features attributed to the coexistence of ferro/ferri/antiferro-magnetic ground state and semiconductor band gap within the same material. Double perovskites with Sr₂NiMO₆ (M = Te, W) structure type have been synthesized using simple, non-toxic and costless aqueous citrate sol-gel route. The reaction yielded phase-pure nanocrystalline powders of two compounds: Sr₂NiWO₆ (SNWO) and Sr₂NiTeO₆ (SNTO). According to the Rietveld refinement of powder X-ray diffraction data at room temperature, Sr₂NiWO₆ is tetragonal (I4/m) and Sr₂NiTeO₆ is monoclinic (C1
