    McQueeney, R. J.; Yethiraj, M.; Chang, S.; Montfrooij, Wouter; Perring, T. G.; Honig, Jurgen M.; Metcalf, P. (American Physical Society, 2008)
    Magnetite (Fe3O4) is a mixed valent system where electronic conductivity occurs on the B site (octahedral) iron sublattice of the spinel structure. Below TV=123   K, a metal-insulator transition occurs which is argued to ...
