The transverse Rashba effect is proposed and investigated by thefirst-principle calculations based on density functional theory in aquasi-one-dimensional antiferromagnet with a strong perpendicularmagnetocrystalline anisotropy, which is materialized by the Gd-adsorbedgraphene nanoribbon with a centric symmetry. The Rashba effect in this systemis associated with the local dipole field transverse to and in the plane of thenanoribbon. That dipole field is induced by the off-center adsorption of the Gdadatom above the hex-carbon ring near the nanoribbon edges. The transverseRashba effect at the two Gd adatoms enhances each other in theantiferromagnetic (AFM) ground state and cancels each other in theferromagnetic (FM) meta-stable state, because of the centrosymmetric atomicstructure. The transverse Rashba parameter is 1.51 eV A. This system shows astrong perpendicular magnetocrystalline anisotropy (MCA), which is 1.4 meV perGd atom in the AFM state or 2.2 meV per Gd atom in the FM state. The origin ofthe perpendicular MCA is analyzed in k-space by filtering out the contributionof the transverse Rashba effect from the band structures perturbed by thespin-orbit coupling interactions. The first-order perturbation of the orbit andspin angular momentum coupling is the major source of the MCA, which isassociated with the one-dimensionality of the system. The transverse Rashbaeffect and the strong perpendicular magnetization hosted simultaneously by theproposed AFM Gd-adsorbed graphene nanoribbon lock the up- (or down-) spinquantization direction to the forward (or backward) movement. This findingoffers a magnetic approach to a high coherency spin propagation inone-dimensionality, and open a new door to manipulating spin transportation ingraphene-based spintronics.
