Abstract

In this study, Spin conductivity of gapped Graphene using Hubbard model is calculated. We obtain Spin conductivity for two cases: in the absence of coulomb interaction and in the presence of coulomb interaction between electrons. It can be seen that for the non-itercting case, by increasing the magnetization, the peaks of Spin conductivity will be shifted towards lower frequencies and the height of them rises. By increasing the energy gap, the peaks of Spin conductivity will be shifted towards higher frequencies and the height of them rises. In the interacting case, plots of Spin conductivity versus frequency have two peaks. One of them belongs to spin up electrons and the other belongs to spin down electrons. By increasing magnetization, the peaks of spin up electrons will be shifted towards lower frequencies and the peaks of spin down electrons will be shifted towards higher frequencies. By increasing the repulsion coulomb interaction and the energy gap, spin up and spin down peaks will be shifted towards higher frequencies.
