快速淬火的三元Ni-Mn-T （T = In, Sn）合金表现出与磁性粒子相关的特征，因此对这两种合金体系进行了XRD、TEM、EDS、SAED和HREM的结构表征。本文报道了一种新型的富锰Heusler化合物，该化合物具有立方晶胞，Ni-Mn-In中α = 0.9150 nm， Ni-Mn-Sn中α = 0.9051 nm，与Ni-Mn-In中α = 0.6094 nm， Ni-Mn-Sn中α = 0.6034 nm的富镍全Heusler化合物共存。对实验结果的进一步分析揭示了这两种化合物之间密切的结构关系。
Rapidly quenched ternary Ni-Mn-T (T = In, Sn) alloys exhibit features associated with magnetic skyrmions, so that XRD, TEM, EDS, SAED and HREM investigations were carried out for structural characterization on the two alloy systems. In this paper, we report a new type of Mn-rich Heusler compound with a cubic unit cell, alpha = 0.9150 nm in Ni-Mn-In and alpha = 0.9051 nm in Ni-Mn-Sn, which coexist with a Ni-rich full-Heusler compound with defects, alpha = 0.6094 nm in Ni-Mn-In and alpha = 0.6034 nm in Ni-Mn-Sn. A further analysis of the experimental results reveals a close structural relationship between these two compounds.
