▎ 摘　　要

Using the transfer matrix method, we theoretically study the electron transport properties in a graphene-based magnetic nanostructure modulated by a Schottky metal (SM) stripe, which can be experimentally realized by depositing a ferromagnetic metal (FM) stripe and a SM stripe on the top and bottom of the monolayer graphene. From the numerical results, we find that the electron transmission and the conductance strongly depend not only on the incident angle of carriers and the strength of the magnetic field, but also on the applied voltage on the SM stripe and the width of the SM stripe as well as the position of the SM stripe. These results may be very helpful for understanding the electron tunneling in graphene and for designing the graphene-based nanodevices. (C) 2014 Elsevier Ltd. All rights reserved.
