## Description

- description: The bilayer structures consisting of Mn3PtN (5 nm)/CoFeB(3 nm) and
    Mn3Pt(5 nm)/CoFeB(3 nm) were fabricated via magnetron sputtering to investigate
    the role of nitrogen on charge-to-spin conversion efficiency in the noncollinear
    antiferromagnets (AFMs). The crystal structure of Mn3PtN (MPN) without N is consistent
    with that of Mn3Pt (MP) with L12-ordered structure, which allows us to study the
    different charge-to-spin conversion efficiency for AFMs with and without N. The
    spin-torque ferromagnetic resonance and second-harmonic Hall measurements were
    performed for both samples. It was revealed that the spin Hall angle (θSH) of
    the MPN with spin polarization in the y direction was observed to be ∼0.033, exceeding
    the corresponding value of MP (∼0.025), which was qualitatively supported by the
    first-principles calculation. These results led us to conclude that N plays a
    crucial role in stabilizing the noncolliear antiferromagnetic structure and creating
    an electronic state advantage for the enhanced θSH.
