Local structural properties of 0.5BiMnO(3)-0.5ATiO(3) (A = Ba or Sr)
Artikel i vetenskaplig tidskrift, 2010

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 Bi3+ cations prefer to adopt an asymmetric coordination due to the influence of the lone-pair electrons.
