## Description

- description: 'The universal oscillation of the tunnel magnetoresistance (TMR) ratio
    as a function of the insulating barrier thickness in crystalline magnetic tunnel
    junctions (MTJs) is a long-standing unsolved problem in condensed matter physics.
    To explain this, we here introduce a superposition of wave functions with opposite
    spins and different Fermi momenta, based on the fact that spin-flip scattering
    near the interface provides a hybridization between majority- and minority-spin
    states. In a typical Fe/MgO/Fe MTJ, we solve the tunneling problem and show that
    the TMR ratio oscillates with a period of ~3Å by varying the MgO thickness, consistent
    with previous and present experimental observations. '
