摘要

NiTiO₃ (NTO) was synthesized via the solid-state reaction method and characterized for its structural, morphological, optical, and multifunctional properties. XRD confirmed its R3 (#148) distorted rhombohedral structure, while FESEM revealed a nanostructured morphology. EDAX verified purity with slight oxygen deficiency. The optical band gap was 2.1(± 0.015) eV, indicating semiconductor potential. FTIR confirmed metal–oxygen bonding. Magnetic measurements showed room-temperature weak ferromagnetism, and ferroelectric analysis highlighted its multifunctionality. These results suggest NTO’s potential for spintronic and optoelectronic applications.
