论文摘要
研究了过渡金属掺杂的Mn $ _3 $ SNC的结构和磁性，目的是了解过渡金属原子对Antiperovskite化合物的磁结构特性的影响。掺杂的Mn $ _ {2.8} $ t $ _ {0.2} $ snc（t = cr，fe，fe，co，ni和cu）化合物显示出一种明显不同的磁性行为，这与过渡金属原子的$ d $ band band tance填充有关。虽然Cr和Fe掺杂的Mn $ _3 $ SNC显示出类似于Mn $ _3 $ SNC的属性，而Co，Ni和Cu掺杂化合物的二相成核表现出缺乏碳和Heusler和Heusler和Do19型六边形结构的二相成核。观察到杂质阶段和主要的替珀酮相之间存在强烈的磁相互作用，从而导致替比洛夫龙岩相的磁结构过渡温度急剧降低和簇状玻璃基态。
The structural and magnetic properties of transition metal-doped Mn$_3$SnC are studied with an aim to understand the effect of transition metal atom on magnetostructural properties of the antiperovskite compound. The doped Mn$_{2.8}$T$_{0.2}$SnC (T = Cr, Fe, Co, Ni and Cu) compounds show a distinctly different magnetic behavior which can be related to electronic filling of the $d$ band of the transition metal atom. While Cr and Fe doped Mn$_3$SnC show properties similar to that of Mn$_3$SnC, the Co, Ni and Cu doped compounds exhibit nucleation of secondary phases which are devoid of carbon and having Heusler and DO19 type hexagonal structure. A strong magnetic interaction is observed between the impurity phases and the major antiperovskite phase leading to a sharp decrease in magnetostructural transition temperature of the antiperovskite phase and a cluster glassy ground state.
