    Freudenbergite - a new example of electron hopping
    (Australian Institute of Physics, 2014-02-06) Cashion, JD; Lashtabeg, A; Vance, ER; Ryan, DH; Solano, J
    Mössbauer spectra of freudenbergite samples with different composition have showed that although the Fe and Ti populate the octahedra randomly, Fe prefers the M(1) site over the M(2) site by approximately 1.3:1. Ti was able to accommodate mixed valence more easily than Fe, but some samples showed dynamic electron hopping in the Fe ions, which also affected the diffuse reflectance in the 400-800 nm region.
