The electronic properties of antimonene, single-layer Sb, are attracting great attention. In this paper, spin transport in armchair antimonene nanoribbon (ASbNR) is investigated. Following the tight-binding model, we calculate both transmission probability and conductance by means non-equilibrium Green's function (NEGF) method. effects an external electric field vertical to ribbon plane explored. Our results indicate that spin-flip rate increases with field. Disorder on addressed considering presence charged impurities. It found impurities also enhance but a lesser extent than out-of-plane
