Local structural properties of 0.5BiMnO3-0.5ATiO3 (A = Ba or Sr).
Neutron total scattering data have been used to probe the long- and short-range structure of 0.5BiMnO(3)-0.5ATiO(3) (A = Ba or Sr). Modelling of the total scattering data, using the reverse Monte Carlo (RMC) method, reveals local disorder that differs substantially from the average structure. Significantly, the Bi(3+) cations prefer to adopt an asymmetric coordination due to the influence of the lone-pair electrons.
