## Description

- description: To expand the potential of 2D materials in memory devices, we investigated
    the orbital torques in the nitride-based 2D-MXene, which is referred to as a post
    graphene and transition-metal dichalcogenides. Epitaxial and polycrystalline Cr2N
    2D-MXene films were developed by reactive nitridation sputtering, and field-free
    perpendicular magnetization switching was achieved with a critical current density
    comparable to W/CoFeB systems. X-ray magnetic circular dichroism revealed that
    this behavior originates from interfacial uncompensated Cr moments, antiparallel
    to the ferromagnet, which act as an efficient spin filter for z-polarized spins.
    Beyond the MXene, efficient spintronic functionalities have been developed in
    nitride-based materials, which is associated with the strong p–d hybridization
    with interstitial nitrogen. These findings motivate the concept of “Nitrospinics,”
    nitrogen-enabled efficient and stable spintronic properties. This talk will highlight
    Nitrospinics-driven advances and their implications for future orbital torque
    memories.
