## Description

- description: YbMnSb2, a topological semimetal with an exotic band structure, has
    recently been found to exhibit potential thermoelectric transport properties in
    its single-crystalline formality. The fabrication of polycrystals, which have
    the advantages of easy synthesis and doping tunability, will advance the transport
    studies of YbMnSb2 but face challenges. Here, we found that the polycrystalline
    YbMnSb2, synthesized using the conventional melting method, unexpectedly exhibits
    obvious impurities due to the competing phase YbMn2Sb2. To avoid the high-temperature
    synthesis, high-quality polycrystalline bulk YbMnSb2, as well as three other RMnSb2
    (R = Sr, Ba, Eu), were successfully prepared by mechanical alloying followed by
    spark plasma sintering. Based on the high-quality polycrystalline samples, it
    was discovered that YbMnSb2 reacts with oxygen during heating in the presence
    of small amounts of oxygen, resulting in MnSb, Yb2O3, and Sb. A similar oxidation
    phenomenon also occurs for the other RMnSb2. This work provides a feasible method
    for synthesizing high-quality RMnSb2 polycrystals, which should also be suitable
    for the other isostructural topological semimetals, paving the way for future
    studies of their transport properties.
