The magnetic and magnetoresistance properties of ultrathin magnetite films grown on MgO substrate

Abstract

We report on the properties of ultrathin 2, 4, 6, and 8 nm epitaxial films of magnetite, Fe3O4, grown on MgO 100 . Atomic force microscopy image and V-I curves suggest that the films at this thickness are still continuous. The resistivity versus temperature results imply that the conductivity mechanism in all these films is similar. The resistivity of 4 nm… (More)
