合成了Mn_（2-x）Zn_xSb（0 ≤x≤ 1）单晶，并研究了它们的磁性和电子输运性质。该材料系统显示丰富的磁相可调的温度和锌成分。此外，两组不同的磁性和电子性能，分离的临界Zn组成ofx= 0.6，被发现。锌少的样品是金属的，其特征在于在磁有序温度下的电阻率跳变，而富锌的样品失去金属性，并显示出可通过磁场调节的金属-绝缘体过渡样功能。我们的研究结果确立了Mn 2-xZnxSb作为一个有前途的材料平台，提供了机会来研究自旋，电荷和晶格自由度的耦合如何控制2D磁体中有趣的输运性质，这是目前广泛关注的话题。
We synthesized single crystals for Mn2-xZnxSb (0 ≤x≤ 1) and studied their magnetic and electronic transport properties. This material system displays rich magnetic phase tunable with temperature and Zn composition. In addition, two groups of distinct magnetic and electronic properties, separated by a critical Zn composition ofx= 0.6, are discovered. The Zn-less samples are metallic and characterized by a resistivity jump at the magnetic ordering temperature, while the Zn-rich samples lose metallicity and show a metal-to-insulator transition-like feature tunable by magnetic field. Our findings establish Mn2-xZnxSb as a promising material platform that offers opportunities to study how the coupling of spin, charge, and lattice degrees of freedom governs interesting transport properties in 2D magnets, which is currently a topic of broad interest.
