## Description

- description: 'We theoretically study the tunnel magnetoresistance (TMR) effect in
    (111)-oriented junctions Co/MgO/Co(111) and Ni/MgO/Ni(111). The Co-based junction
    is shown to have a TMR ratio over 2000%, which is one order higher than that of
    the Ni-based one. The high TMR ratio is attributed to the interfacial resonance
    effect: the interfacial d–p antibonding states are formed close to the Fermi level
    in the majority-spin channel and these states in both interfaces resonate with
    each other. This differs essentially from the conventional coherent tunneling
    mechanism of high TMR ratios in Fe(Co)/MgO/Fe(Co)(001).'
