## Description

- description: Mg3Bi2 is a candidate Type-II nodal-line semimetal (a novel category
    of topological semimetals). However, the exotic transport properties of Mg3Bi2
    single crystals are yet to be elucidated. Herein, we report the magnetotransport
    properties of an n-type Mg3Bi2 single crystal grown from a melt. The results revealed
    that the single crystal exhibited a very large nonsaturating magnetoresistance
    (5000%) under an 8 T field, significantly exceeding that of polycrystals. The
    combined analysis of Shubnikov–de Haas (SdH) oscillations, Hall resistivity, and
    first-principles calculations suggest that SdH oscillations originate from trivial
    electron bands rather than hole bands, which contain an almost linear dispersion.
    We confirmed that the electron mobility reached 10000 cm2/Vs by analyzing Hall
    resistivity and magnetoresistance based on a two-band model. The electron/hole
    concentration and mobility were used to investigate the measured transport properties,
    such as the Nernst coefficient. Overall, these results are critical for elucidating
    the electronic structure and transport properties of Mg3Bi2.
