The anisotropic magnetoresistance (AMR) of a Ta (5nm)/MgO (3nm)/Ni81Fe19(10nm)/MgO (2nm)/Ta (3nm) film with MgO-Nano Oxide Layer (NOL) increases dramatically from 1.05% to 3.24% compared with a Ta (5nm)/Ni81Fe19(10nm)/Ta (3nm) film without the MgO-NOL layer after annealing at 380°C for 2h. Although the MgO destroys the NiFe (111) texture, it enhances the specular electron scattering of the conduction electrons at the NOL interface and suppresses the interface reactions and diffusion at the Ta/NiFe and NiFe/Ta interfaces. The NiFe (111) texture was formed after the annealing, resulting in a higher AMR ratio. X-ray photoelectron spectroscope results show that Mg and Mg2+were present in the MgOxfilms.
