The paper entitled "Interface-driven giant tunnel magnetoresistance in (111)-oriented junctions" has been published in Phys. Rev. B.

In this work (Masuda et al., 2020), Masuda et al. theoretically predicted unprecedentedly large TMR based on a new mechanism in unconventional (111)-oriented magnetic tunnel junctions (MTJs). Through the first-principles transport calculation, they found that in the Co/MgO/Co(111) MTJ, the interfacial d-p antibonding states are formed close to the Fermi level and their resonance (so-called “interfacial resonance”) yields a quite high TMR ratio. This is in sharp contrast to the case of conventional (001)-oriented MTJs, where bulk electronic states mainly contribute to TMR. These findings not only advance the fundamental understanding on TMR but also give a new insight to experimentally explore wider range of MTJs for higher TMR ratios.
