Unlike other transition metals alloyed with a non-magnetic metal, alloys of Ni behave rather differently. This is because of the fragility of the local magnetic moment on Ni. NiMo and NiW do not show any spin-glass phase. However, addition of Fe can bolster the moment on Ni. We wish to study whether the alloy Fe(3.3)Ni(83.2)Mo(13.5), chosen near a composition where mean-field estimates suggest there could be a spin-glass phase, shows such a phase or not.
与其他与非磁性金属合金化的过渡金属不同，Ni 的合金表现出相当不同的行为。这是由于 Ni 上局部磁矩的脆弱性。NiMo 和 NiW 不显示任何自旋玻璃相。然而，添加 Fe 可以增强 Ni 上的磁矩。我们希望研究在平均场估计表明可能存在自旋玻璃相的组成附近选择的合金 Fe(3.3)Ni(83.2)Mo(13.5)是否显示出这样的相。
