摘要：
We investigate tunnel magneto-resistance (TMR) ratio in superlattice magnetic tunnel junctions with diverse barrier-heights (DSMTJs) including linear, Gaussian, Lorentzian, and Poscl-Teller profiles. Transmission functions are computed by non-equilibrium Green's function method in the tight-binding model. The results for the DSMTJ are compared to those for regular types as higher TMR ratios are achieved in the former in comparison with the latter. Therefore, the present findings can be utilized to improve in the field of spintronics.
