The magnetic properties of the two-dimensional triangular-lattice compound HoZn₃P₃ synthesized under high pressure are reported. We have performed magnetization, electrical resistivity, and specific heat measurements of the compound. The magnetic susceptibility shows an anomaly at around 5 K attributed to a magnetic ordering. The resistivity reveals metallic behavior and a minimum at around 17 K (T_min); then, an upturn of the resistivity below T_min shows a logarithmic dependence of the temperature (−log T). Furthermore, the resistivity exhibits a sharp drop at 4.5 K, which corresponds to the magnetic ordering. The upturn of the resistivity at low temperatures was suppressed by a magnetic field. The specific heat shows a clear peak at T_M = 4.5 K due to the magnetic ordering. The T_M shifts towards a high temperature at a rate of 0.06 K/kOe. A large γ value of 199 mJ/mol K² was observed, and the γ value increases as the magnetic field increases and shows a maximum at 60 kOe. We demonstrate the crucial role of the hybridization between 4f electrons and conduction electrons depending on the distance between rare-earth R atoms in determining the transport and magnetic properties of RZn₃P₃.

高压制备层状稀土磷化锌HoZn3P3的磁性能

报道了在高压下合成的二维三角晶格化合物HoZn ₃ P ₃的磁性能。我们已经对化合物进行了磁化、电阻率和比热测量。磁化率在 5 K 附近显示异常，这归因于磁排序。电阻率显示出金属行为，并且在 17 K ( T _min )附近具有最小值；然后，低于T _min的电阻率上升显示温度的对数依赖性（-log T）。此外，电阻率在 4.5 K 处急剧下降，这对应于磁序。低温下电阻率的上升被磁场抑制。由于磁性有序，比热在T _M = 4.5 K处显示出明显的峰值。所述Ť_中号朝0.06 K /千奥斯特的速率高的温度变化。观察到199 mJ/mol K ²的大γ值，γ值随着磁场的增加而增加，并在 60 kOe 处出现最大值。我们证明了 4 f电子和传导电子之间杂化的关键作用取决于稀土R之间的距离原子在确定R Zn ₃ P ₃的传输和磁性能中。
