High-temperature order disorder in (Fe0.5Mn0.5)(2)SiO4 and (Mg0.5Mn0.5)(2)SiO4 olivines: An in situ neutron diffraction study
Time-of-flight neutron powder diffraction has been used to determine the time-temperature dependence of M-site occupancies and crystal structures of MgMnSiO4 and FeMnSiO4 olivines between room temperature and 1000°C. In each sample Mn shows a preference for the M2 site at low temperature, but become...
