Zener Double Exchange from Local Valence Fluctuations in Magnetite
(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 ...
