Reverse Monte Carlo refinements using a combined real-space fit of the neutron/X-ray total scattering pair-distribution function and the extended X-ray absorption fine structure were developed and implemented as an extension to the public domain computer software RMCProfile. The effectiveness of the method was tested using perovskite Ca(Zr,Ti)O3 solid solutions.

The lattice parameters of Mg1−xFexO (x = 0.2, 0.3, 0.4) in the range P < 10.3 GPa and 300 < T < 986 K have been determined by time-of-flight neutron powder diffraction. Fitting all data simultaneously to a P–V–T–x equation of state leads to values for the temperature derivative of the isothermal incompressibility, ∂KT/∂T, and the isothermal Anderson–Grünseisen parameter, δT, of −0.024 (9) GPa K−1 and 4.0 (16) at 300 K.
