摘要: We study magnetic proximity effect induced low-energy spin transport in normal/ferromagnetic junction of semi-infinite zigzag graphene nanoribbon. Due to the absence of spin flip in single interface, the spin transfer in this model can be described by the “two-spin channel” model. We identify each spin channel as either perfect conducting or non-conducting channel. This feature leads to spin filter in symmetric zigzag graphene nanoribbon and spin precession in antisymmetric zigzag graphene nanoribbon, and helps to determine exchange-splitting intensity directly, even without an external auxiliary bias.
