Abstract

Electric transport properties have been studied for Fe3O 4 thin films with current perpendicular to plane geometry, aiming at development of oxide spintronics devices. Excellent conductivity comparable to a bulk single crystal was attained by optimizing an under layer material and film deposition condition. A novel conductivity switching, up to three orders of magnitude, was observed. The threshold value of electric field for switching and its temperature dependence were investigated.
