| Outline of Final Research Achievements |
We achieved the extremely low second-order temperature coefficient of resistance, -0.20 ppm/K2, with the peak temperature of 307 K by co-doping of Cu, Mn and In to Mn3AgN, which is comparable to widely-used standard-resister material, manganin. The drift rate of resistance was suppressed to less than several ppm/year by optimizing the methods of contact formation. We also successfully fabricated an epitaxial film of prototypical material Mn3CuN using a high-magnetic-field sputter method.
