Structural evolution of bismuth sodium titanate induced by A-site non-stoichiometry: Neutron powder diffraction studies

I. -K. Jeong, Y. S. Sung, T. K. Song +2

We performed neutron powder diffraction measurements on (Bi${}_{0.5}$Na${}_{0.5+x}$)TiO${}_3$ and (Bi${}_{0.5+y}$Na${}_{0.5}$)TiO${}_3$ to study structural evolution induced by the non-stoichi…
