A novel multicomponent perovskite was synthesized by substituting 5 cations in the A-site of BaTiO3 lattice. The compound underwent 5 hours of ball milling, followed by annealing at 800 degrees C for 2 hours, and then sintered at 1200 degrees C for 2 hours to form the cubic perovskite phase. The band gap of the compound was found to be 2.94 eV with a dielectric constant value of 270.
The synthesis of a novel multicomponent perovskite was carried out by substituting 5 cations in the A-site of BaTiO3 lattice. The mechanochemical synthesis involved 5 h of ball milling followed by annealing at 800 degrees C for 2 h and the compound was sintered at 1200 degrees C for 2 h to form the cubic perovskite phase adopting the Pm (3) over barm space group. The lattice parameter was found to be 0.391 nm. The reduction in the tetragonality and the local distortion in the compound were observed in the 2D charge distribution maps. The band gap of the compound was found to be 2.94 eV with a dielectric constant value of 270. Ferroelectric hysteresis loops were recorded and the leakage current density was found to be in the order of 10(-5) A/cm(2).
