自超导磁体发展以来，高磁场已成为通过排列材料中的晶体来获得织构结构的有效方法之一。众所周知，强磁场可以使具有磁各向异性的晶体排列。然而，晶体在液体介质中的布朗运动和重力对晶体取向的影响尚不清楚。本研究发现，在晶体布朗运动和重力的作用下，在高磁场的作用下，存在一定尺寸范围的晶体颗粒可以排列。此外，考虑到这些因素，对高磁场下的晶体排列进行了理论分析，阐明了导电性能好和导电性能差的弱磁性材料中的晶体排列现象。
Since superconducting magnet was developed, high magnetic field has been used as one of the effective ways to get textured structures by aligning crystals in materials. It is well known that the high magnetic field can align crystals having magnetic anisotropy. However, effects of Brownian motion of crystals in liquid medium and gravity force on the crystal alignment are not well known. In this study, it has been found that there is a size range of crystal particles in which the crystals can be aligned by high magnetic field under actions of Brownian motion of crystals and gravity force. Moreover, by taking account of these factors, theoretical analysis of crystal alignment under high magnetic field has been carried out to elucidate the phenomena of the crystal alignment in both feeble magnetic materials having well or poor electric conductivity.
