Abstract

Neutron total scattering data have been used to probe the long- and short-range structure of 0.5BiMnO3–0.5ATiO3 (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 Bi3+ cations prefer to adopt an asymmetric coordination due to the influence of the lone-pair electrons.
