Local structure of Sr-doped multiferroic bismuth ferrite

Abstract: Bismuth ferrite, BiFeO3, is a much-studied ceramic showing both dielectric and magnetic ordering at relatively high temperatures. In order to improve its properties there has been much interest in doping BiFeO3, but rarely has there been structural characterisation of these materials. We have shown that it is possible to replace bismuth ions by strontium together with oxygen vacancies. Increasing composition of strontium lowers the transition temperatures so that the high-symmetry cubic phase becomes stable at room temperature. This is exciting because we cannot reach this phase by heating pure BiFeO3. We will use neutron total scattering with Reverse Monte Carlo analysis to study the local structure fluctuations in materials with various strontium compositions in both ferroelectric and paraelectric phases for comparison.
