| Research Abstract |
Physical properties of Fe3Mo3N and(Fe1-xCox)_3Mo_3N systems have been studied comprehensively. In this study, a non-Fermi-liquid behavior without any tuning such as physical pressure and/or chemical doping was found for the first time. NFL behavior suggests the existence of quantum critical point in the vicinity of pure Fe_3Mo_3N. Field and substitution induced ferromagnetic phases were found as was expected. The constructed phase diagram is not trivial, suggesting the effect of geometrical frustration inherent in theη-carbide-type compound. Related compound Fe_3W_3N(a ferromagnet TC=110 K) and Fe_6W_6N(an antiferromagnet TN=75 K) were synthesized by HIP method for the first time.
