Structural, magnetic and transport properties of Mn3.1Sn0.9 and Mn3.1Sn0.9N compounds

Synthesis of a Nitrogen-Stabilized Hexagonal Re3ZnNx Phase Using High Pressures and Temperatures

“…On the basis of these considerations, nitrogen in the present case is also, placed interstitially in the pure Re octahedra. For the case of the D0 19 structure, increasing the hydrogen or deuterium content ultimately causes a phase transition to the Cu 3 Au cubic antiperovskite modification. , For the case of nitrogen, attempts to incorporate it into an existing D0 19 structure resulted in the Cu 3 Au structure, , that is, there was no stability field for a nitrogen-containing hexagonal superlattice structure prior to this work. A second seminal difference from the previous cases involving hexagonal modifications is that reactions between the constituent elements making up the hexagonal modifications could occur with or without the presence of the interstitial additions, whereas in the present case, Re does not react with Zn either at ambient or at the highest pressures and temperatures of our experiments.…”

“…Several previous ambient pressure studies on the cubic antiperovskite structures reveal that smaller ions including hydrogen, deuterium, carbon, and nitrogen ions are all incorporated interstitially in the octahedral interstitial position. [19][20][21][22][23][24][25][26][27][28][29] Prior to this work, for the D0 19 and D0 24 hexagonal modifications, the only reports, to our knowledge, of interstitial ions entering the structures were hydrogen for both modifications and deuterium for D0 19 . [28][29][30] In all the above cases, invariably, the ions enter the octahedral site with the vertices occupied solely by the transition-metal ions.…”

Lattice, magnetic and electronic transport behaviors of Ge-doped Mn3XC (X=Al, Zn, Ga)

“…These properties are closely correlated with their structure and magnetic phase transition. In addition, some of the antiperovskite compounds showed abnormal electronic and magnetic transport behaviors and lattice variation with changing temperature [14,15]. So, it is necessary to study the structure, electronic and magnetic transport of the cubic antiperovskite compounds.…”

Metal‐Rich Ternary Perovskite Nitrides

“…In cubic Mn 4– x Sn x N the magnetic moment as well as the Curie temperature drops with increasing substitution , . For Mn 3.1 Sn 0.9 N, a ferromagnetic component in the temperature range of 5–370 K and a spin‐reorientation at about 280 K was described …”

“…[158a] Recently, cubic Co 3 SnN was synthesized after prediction of its stability via a high‐throughput screening by DFT methods , . Cubic Co 3 InN and Co 3 GeN show spin‐glass behavior, probably as a result of minor disorder or – more likely – main‐group metal vacancies , , . For Co‐rich perovskite nitrides with iron see the comments in paragraph 4.2.1.…”
