By performing first-principle quantum transport calculations, we predict a giant magnetoresistance in zigzag silicene nanoribbons (ZSiNRs) connecting two semi-infinite silicene electrodes through switch of the edge spin direction of ZSiNRs. Spin-filter efficiency of both the antiferromagnetic and ferromagnetic ZSiNRs is sign-changeable with the bias voltage. Therefore, potential application of silicene in spintronics devices is suggested.
通过第一性原理量子输运计算，我们预测了通过改变 ZSiNRs 边缘自旋方向，在连接两个半无限大硅烯电极的锯齿型硅烯纳米带（ZSiNRs）中会产生巨大的磁电阻。对于反铁磁和铁磁 ZSiNRs，自旋过滤效率都随偏压发生符号变化。因此，建议将硅烯应用于自旋电子器件中。
