Abstract
The near zero temperature coefficient of resistivity (NZ-TCR) in Mn-based antiperovskite Mn 3Ni 1-xCu xN is reported. The temperature range of NZ-TCR is controllable by changing Cu content. Further, the TCR value of 0.09 ppm K -1 was obtained in Mn 3Ni 0.5Cu 0.5N over a broad temperature range around room temperature. The anomalous resistivity change of Mn 3Ni 1-xCu xN from metal-like to NZ-TCR behavioris apparently due to a magnetic transition. The possible reason for the formation of NZ-TCR is interpreted on the basis of spin-disorder scattering. © 2011 American Institute of Physics.
