Abstract:The electronic transport properties of Mn3SnC and Mn3SnC0.5N0.5 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 Mn3SnC and Mn3SnC0.5N0.5, respectively. This phenomenon could be understood by the Labbe–Jardin tight binding approximation model.
