We present the comparative measurements of the angular dependence of the anisotropic magnetoresistance (AMR) of magnetite (Fe3 O4) films on MgO(001) nonvicinal and vicinal substrates (2.86° miscut along the 〈 100 〉 direction). The AMR behavior for current parallel and perpendicular to the direction of step edges is quite similar to that of nonvicinal Fe3 O4 films for temperatures above the Verwey transition (TV). However, we observed a dramatic change in the symmetry of the AMR's angular response below TV for the vicinal sample, which depends on the direction of current with respect to the step edges. The results highlight the influence of step edge induced spin disorder on the transport properties below Verwey transition.
