- title: Large Tunneling Magnetoresistance in Perpendicularly Magnetized Magnetic
    Tunnel Junctions Using Co75Mn25/Mo/Co20Fe60B20 Multilayers

## Description

- description: "We study the magnetic and electrical transport properties of magnetic
    tunnel junctions (MTJs) consisting of a Co3Mn/Mo/CoFeB multilayer prepared using
    a mass-production-compatible magnetron sputtering system. The Co3Mn/Mo/CoFeB multilayer
    sandwiched between two MgO layers exhibits remarkable perpendicular magnetic anisotropy,
    and a uniaxial magnetic anisotropy constant as large as 0.2 MJ/m3 is achieved
    by optimizing the Co3Mn layer thickness as well as the annealing temperature.
    The current-in-plane tunneling measurement reveals a large tunneling magnetoresistance
    of over 100% in perpendicularly magnetized MTJs. These experimental results indicate
    the applicability of Co3Mn alloy for magnetic random access memory devices.\r\n"
