Electrical property of nanocrystalline γ-Fe2O3 under high pressure

Using a microcircuit fabricated on a diamond anvil cell, in situ conductivity measurements on nanophase (NP) γ-Fe2O3 are obtained under high pressure. For NP γ-Fe2O3, the abrupt increase in electrical conductivity occurs at a pressure of 21.3GPa, corresponding to a transition from maghemite to hemat...
