Structural characterization (differential scanning calorimetry, DSC, and X-ray diffraction, XRD) and temperature dependence of the magnetization are reported in Ni₈₀Si₁₀B₁₀ and Ni₇₅Si₁₅B₁₀ alloy ribbons produced by rapid solidification. XDR and DSC measurements lead to confirm the amorphous character of Ni₇₅Si₁₅B₁₀ alloy while the Ni₈₀Si₁₀B₁₀ alloy presents a mixture of amorphous and crystalline (Nickel face-centered cubic) phase. Low-temperature magnetization dependencies were analyzed in terms of spin-wave excitation and fluctuations of the exchange interaction. While both mechanisms are relevant for the high Ni-content alloy, fluctuations of exchange could be ascribed as mechanism for low Ni-content alloy. The effect of annealing (523 and 623 K during 1 h) on the magnetic behavior is also presented. Thus, annealing of Ni75 sample at 623 K also results in appearance of highly magnetic Ni phase.

在通过快速凝固制备的Ni ₈₀ Si ₁₀ B ₁₀和Ni ₇₅ Si ₁₅ B ₁₀合金薄带中，报道了磁化强度的结构表征（差示扫描量热法，DSC和X射线衍射，XRD）和温度依赖性。XDR和DSC测量可确定Ni ₇₅ Si ₁₅ B ₁₀合金的非晶态特性，而Ni ₈₀ Si ₁₀ B ₁₀的非晶态特性合金呈现出非晶态和晶态（镍面心立方）相的混合物。根据自旋波激发和交换相互作用的波动分析了低温磁化依赖性。虽然两种机理都与高Ni含量合金有关，但是交换的波动可以归因于低Ni含量合金。还介绍了退火（1小时内的523和623 K）对磁性能的影响。因此，Ni75样品在623 K退火也导致出现高磁性的Ni相。
