When using the magnetization force ((chi=B・)B/mu_0), a magnetic susceptibility (chi) is important. In this work, non magnetic metals whose values of chi are much smaller than those of ferromagnetic materials were used for experiments. Also, the values of chi are large different from one material to others. Furthermore, chi of diamagnetic materials is negative, and also values of chi are different in crystal orientation. In this experiment a metal sample was heated and vaporized in the strong magnetic field, 5.5T by a YAG laser beam. The deposited metal on a glass surface was diffracted by X-ray to study the effect of magnetization force on crystal orientation.The distribution of the magnetic field in a bore of the super conducting magnet was measured. By changing the positions of a substrate and a sampie stage, the characteristics of deposited materials was measured.It is found that the deposition rate can be controlled by changing the intensity of magnetic field and the surface aspect of deposited metal becomes rough in a magnetic field and smooth in a non magnetic field. It is noticed that the strong magnetic field can aligns the crystal orientation of Zn, Bi and Mn films.

当使用磁化力（（chi=B·）B/μ_0）时，磁化率（chi）是重要的。在这项工作中，非磁性金属的chi值比铁磁材料的chi值小得多，用于实验。此外，chi的值从一种材料到其他材料有很大的不同。此外，抗磁性材料的chi是负的，并且chi的值在晶体取向上也不同。在5.5T强磁场中，利用YAG激光对金属样品进行加热汽化。用X射线衍射法研究了玻璃表面沉积金属的磁化力对晶体取向的影响，测量了超导磁体内腔中的磁场分布。通过改变基片和样品台的位置，测量了沉积材料的特性，发现通过改变磁场强度可以控制沉积速率，沉积金属表面在磁场中变得粗糙，在无磁场时变得光滑。研究发现，强磁场可以使Zn、Bi和Mn薄膜的晶体取向发生调整。
