Spin-dependent quantum transport properties in twisted graphene is calculated using density functional theory (DFT) and non-equilibrium Green’s function (NEGF) formulation. Twisting increases the band gap and reduces the spin transport in twisted graphene. At low bias, twisting restricts any spin-up current in antiparallel configuration (APC) which results in higher magnetoresistance (MR), and at higher bias, twisting increases the spin-up current slightly, resulting in lower MR. The MR obtained in twisted graphene at low biases is greater than that of pristine graphene. High spin filtration is observed in parallel configuration and APC for twisted graphene at higher biases which is greater than that of pristine graphene, but at low voltages, pristine gives higher spin filtration than twisted graphene.
