在高达13 kbar的压力下，测量了压力对mn3gac、mn3znc和mn3snc的磁转变温度的影响。得到转变温度的压力导数为：Mn 3 GaC的d T T /d P =-3.5 K/kbar和d T C /d P =0.4 K/kbar， Mn 3 ZnC的d T T /d P =-0.9 K/kbar和T C /d P =0， Mn 3 SnC的d T C /d P =-1.9 K/kbar，其中T T和T C分别为磁序序转变温度和居里温度。在高于3kbar的压力下，m3gac中会产生中间磁相(I)。三相点（antiferror ./I/Ferro.）为T c =158 K, P c =3 kbar。测量了磁化率、磁化率和晶格参数的温度变化。
The pressure effect on the magnetic transition temperatures of Mn 3 GaC, Mn 3 ZnC and Mn 3 SnC were measured under pressures up to 13 kbar. The pressure derivatives of the transition temperatures are obtained to be d T t /d P =-3.5 K/kbar and d T C /d P =0.4 K/kbar for Mn 3 GaC, d T t /d P =-0.9 K/kbar and T C /d P =0 for Mn 3 ZnC and d T C /d P =-1.9 K/kbar for Mn 3 SnC, where T t and T C are the magnetic order-order transition temperature and the Curie temperature, respectively. An intermediate magnetic phase (I) is induced in Mn 3 GaC under pressures above 3 kbar. The triple point (Antiferro./I/Ferro.) was determined to be T c =158 K and P c =3 kbar. The temperature variations of magnetization, magnetic susceptibility and latlice parameter were also measured.
