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 GPa.At ambient pressure,an abrupt increase of resistance occurs around the temperature of magnetic phase transition in both samples.The 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),respectively.This phenomenon could be understood by the Labbe–Jardin tight binding approximation model.
