摘要：

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.
