论文摘要
$ _ {25} $ in $ _ {25} $ in Stoichiotric ni $ _ {50} $ Mn $ _ {25} $从稳定的Ferromagnetic usustenitic地基状态转变为不稳定的Martensenitic基层状态，具有与MN相比，没有任何前开发式培训阶段的逐渐替代。在Ni $ _ {50} $ _ {50} $ _ {25+X} $中，缺乏过渡阶段，例如$ _ {25+X} $，解释为解释是铁磁性立方结构的能力，可以适应由原子质和MN的原子质差异引起的晶格差异。除了$ x $ = 8.75的临界值之外，尽管形成了铁磁和反铁磁簇，但合金还是经历了马氏体转换，并且是超级自旋玻璃状态的外观。
The stoichiometric Ni$_{50}$Mn$_{25}$In$_{25}$ Heusler alloy transforms from a stable ferromagnetic austenitic ground state to an incommensurate modulated martensitic ground state with a progressive replacement of In with Mn without any pre-transition phases. The absence of pre-transition phases like strain glass in Ni$_{50}$Mn$_{25+x}$In$_{25-x}$ alloys is explained to be the ability of the ferromagnetic cubic structure to accommodate the lattice strain caused by atomic size differences of In and Mn atoms. Beyond the critical value of $x$ = 8.75, the alloys undergo martensitic transformation despite the formation of ferromagnetic and antiferromagnetic clusters and the appearance of a super spin glass state.
