## Description

- description: Antiferromagnetic Mn3X (X = Sn, Ge, Ga, and Pt) possessing non-collinear
    spin structures with Kagome lattices have attracted increasing interest because
    of their unique properties, such as significant anomalous Hall and magneto-optical
    Kerr effects. Recent advances in spintronic devices that use non-collinear antiferromagnets
    have inspired research into various materials for exploiting their potential.
    In this study, we investigated the magnetic and magneto-transport properties of
    (1-100)-oriented epitaxial and polycrystalline Mn3Ge films deposited by magnetron
    sputtering. Anomalous Hall conductivity monotonically decreases with temperature
    in an epitaxial Mn3Ge film, whereas the polycrystalline sample demonstrates a
    different trend. Furthermore, we obtained a large in-Kagome-plane uniaxial magnetic
    anisotropy of epitaxial Mn3Ge above ambient temperature, thereby leading to higher
    thermal stability and robustness against the external field. Our results indicate
    the potential of Mn3Ge for future functional, high-speed, and high-density spintronics
    devices using antiferromagnets.
