In Ni/Hf multilayrs of lambda>440A,R(+) shows the properties of an amorphous structure, although we can observe the diffraction peaks of Ni and Hf with X-ray diffraction method.This reveals that the Hf layrs, which are prepared by the magnetron sputtering, contain many defects and those structures are disordered much.The power spectrum shows three resonant peaks, which correspond to the hcp structure of Hf metal.It is known that the power spectrum is composed of the component normal to the surface of the multilayr and the random component.On the other hands, in Ni/Hf multilayr of lambda<110A,the X-ray diffraction has a broad distribution and the power spectrum of TDPAC is distributed broadly, These results reveal that this multilayr has the amorphous sturctvre at room temperature.

在λ> 440的Ni/Hf多层膜中，虽然用X射线衍射方法可以观察到Ni和Hf的衍射峰，但R（+）仍表现为非晶态结构，这表明磁控溅射制备的Hf层中含有大量的缺陷，结构非常无序，功率谱显示出三个共振峰，其功率谱由垂直于多层膜表面的分量和无规分量组成，而在λ <110的Ni/Hf多层膜中，TDPAC的X-射线衍射谱呈宽谱分布，功率谱呈宽谱分布，表明该多层膜在室温下具有非晶态结构。
