- Abstract
In this report, solid solutions of (1−x)Bi1/2Na1/2TiO3+xSrNiO3-δ materials were synthesized by a chemical method. X-ray diffraction and Raman scattering were used to study the structural properties of the (1−x)Bi1/2Na1/2TiO3+xSrNiO3-δ solid solutions. All studied samples had rhombohedral symmetry, where the Sr and Ni cations tended to randomly incorporate with the host Bi1/2Na1/2TiO3 lattices during the formation of solid solutions. The random incorporation of Sr and Ni cations into the host lattices resulted in structural distortion and reduced the optical band gap from 3.04 eV for the pure Bi1/2Na1/2TiO3 to 2.63 eV for the 9 mol.% SrNiO3-δ-modified Bi1/2Na1/2TiO3 sample. The complex magnetic properties of (1−x)Bi1/2Na1/2TiO3+xSrNiO3-δ system were investigated as a function of SrNiO3-δ concentrations. We expected that our simple and flexible method could be used to integrate the ferromagnetic properties in current advanced functional lead-free materials.
