Structure, optical and magnetic properties of new Bi_0.5Na_0.5TiO₃- SrMnO_3-δ solid solution materials.

ABSTRACT: The new Bi_0.5Na_0.5TiO₃-SrMnO_3-δ solid solution materials were fabricated via sol-gel method. The random incorporation of Sr and Mn cations into host lattice of Bi_0.5Na_0.5TiO₃ resulted in structural distortion and influenced on the reduction of the optical band gap from 3.07 eV to 1.81 eV for pure Bi_0.5Na_0.5TiO₃ and 9 mol% SrMnO_3-δ solid solution into Bi_0.5Na_0.5TiO₃. The magnetic properties of Bi_0.5Na_0.5TiO₃ materials at room temperature were tuned via compensation of diamagnetic material with weak-ferromagnetism to ferromagnetism with low SrMnO_3-δ content and combination of paramagnetism/antifer
