The intermetallic compound Eu[Formula: see text]In[Formula: see text]Sb[Formula: see text], an antiferromagnetic material with nonsymmorphic crystalline structure, is investigated by magnetic, electronic transport and specific heat measurements. Being a Zintl phase, insulating behavior is expected. Our thermodynamic and magnetotransport measurements along different crystallographic directions strongly indicate polaron formation well above the magnetic ordering temperatures. Pronounced anisotropies of the magnetic and transport properties even above the magnetic ordering temperature are observed despite the Eu[Formula: see text] configuration which testify to complex and competing magnetic interactions between these ions and give rise to intricate phase diagrams discussed in detail. Our results provide a comprehensive framework for further detailed study of this multifaceted compound with possible nontrivial topology.
Eu[Formula: see text]In[Formula: see text]Sb[Formula: see text] 是一种反铁磁材料，具有非对称晶体结构的金属间化合物，通过磁性、电子输运和比热测量对其进行了研究。作为 Zintl 相，预计其具有绝缘行为。我们沿着不同晶向的热力学和磁输运测量强烈表明，在磁性有序温度以上形成了极化子。尽管 Eu[Formula: see text]构型，但在磁性有序温度以上仍观察到磁性能和输运性能的显著各向异性，这证明了这些离子之间存在复杂且相互竞争的磁相互作用，并导致了详细讨论的复杂相图。我们的结果为进一步详细研究这种具有可能非平凡拓扑的多方面化合物提供了一个全面的框架。
