We have measured x-ray absorption near edge structure (XANES) spectra of mechanically alloyed ZrNi near Ni and Zr K edges as a function of milling time. The x-ray diffraction shows that the system is transformed into an amorphous phase by milling for about 60 h. With increasing the milling time, a small absorption near the Ni threshold rises and finally forms a peak in the amorphous phase, while an absorption near the Zr threshold shows a gradual decrease. The peak of the Ni K edge reflects 3d character strongly hybridized with 4p states, while the absorption of the Zr K edge comes from states having a 4d orbital character.
我们测量了机械合金化的ZrNi在Ni和Zr K边附近的x射线吸收近边结构（XANES）光谱，作为研磨时间的函数。x射线衍射表明，通过研磨约60小时，该体系转变为非晶相。随着研磨时间的增加，Ni阈值附近的一个小吸收峰上升，最终在非晶相中形成一个峰，而Zr阈值附近的吸收则逐渐降低。Ni K边的峰强烈反映了与4p态强烈杂化的3d特征，而Zr K边的吸收来自具有4d轨道特征的态。
