Abstract:
The magnetoresistance sMRd studies of magnetite thin films deposited on vicinal MgO substrates
show an enhanced MR along the miscut direction as compared to the direction perpendicular to it.
The MR anisotropy increases with the decrease in temperature and peaks at the Verwey transition.
The increase in magnetoresistance and anisotropy behavior is attributed to the formation of a greater
number of out-of-plane shifted antiphase boundaries due to the step edges on vicinal MgO
substrates. These local electronic and spin structure modifications at the APBs introduce additional
spin scattering and are responsible for the increase in MR along the miscut
