| 中文摘要 | We propose and theoretically investigate an interesting and potentially very attractive magnetic tunnel junction FePt/NaCl/FePt(001) for spintronics. It is attractive because the strain at the FePt/NaCl interface is relatively small and, as a result, spin injection from the FePt metal to the NaCl barrier is significant and thus a potentially large TMR ratio can be obtained. The electronic bands with the Delta(1) symmetry of L1(0) FePt cross the Fermi level for both the majority-spin and minority-spin channels, and the evanescent state with the Delta(1) symmetry dominates the electron transmission through the fcc NaCl barrier. Very respectable values of the tunnel magnetoresistance ratio are predicted. The microscopic physics of quantum transport in this system is systematically analyzed and understood.
