	我们通过固态反应法制备了多晶Mn<sub>3</sub>Cu<sub>0.5</sub>Zn<sub>0.5</sub>N样品。交流磁化率测量表明其在158 K附近发生了磁转变。通过活塞圆筒式大体积压机施加压力，我们测量了最高2.4 GPa下的交流磁化率和电阻随温度的变化情况。研究发现随着压力的增大，磁转变温度持续增加，压力有助于稳定Mn<sub>3</sub>Cu<sub>0.5</sub>Zn<sub>0.5</sub>N样品的磁有序态。<br />
Polycrystalline samples Mn<sub>3</sub>Cu<sub>0.5</sub>Zn<sub>0.5</sub>N were prepared by solid-state reaction. AC susceptibility and electronic transport properties of Mn<sub>3</sub>Cu<sub>0.5</sub>Zn<sub>0.5</sub>N were measured under pressure up to 2.4 GPa. AC susceptibility measurements show that the magnetic transition took place in the vicinity of 158 K. With the enlargement of the pressure, the magnetic transition temperature continues to increase, indicating that the pressure helps to stabilize the magnetically ordered state in Mn<sub>3</sub>Cu<sub>0.5</sub>Zn<sub>0.5</sub>N.
