摘      要：The electronic transport properties of Mn_(3)SnC and Mn_(3)SnC_(0.5)N_(0.5) were measured under pressures up to 1.8 *** ambient pressure,an abrupt increase of resistance occurs around the temperature of magnetic phase transition in both *** transition temperature TC from paramagnetic to ferrimagnetic state decreases linearly at rates of 12.6 and 6.3 K/GPa with pressure for Mn_(3)SnC and Mn_(3)SnC_(0.5)N_(0.5),*** phenomenon could be understood by the Labbe–Jardin tight binding approximation model.
