Abstract

High magnetic filed can affect not only ferromagnetic materials but also non-magnetic ones. In general, materials have a crystal magnetic anisotropy where a magnetic susceptibility is different in each crystal direction. So that the utilization of this property can control the crystal orientation by imposition of the high magnetic field. Up to now, the possibility of magnetic orientation by imposition of the high magnetic field has been studied, it was said that existence of crystal magnetic anisotropy and a low viscosity are essential. Then, substance which has crystal magnetic anisotropy can control the crystal orientation by heating up to liquid and solid zone which is a low viscosity.
It is found that the high magnetic field can control the crystal orientation of Zinc or Bismuth-Tin alloy, non-magnetic material, by reheating in a solidification process. These experimental results can be explained by taking into account of a magnetic energies due to the crystal magnetic anisotropy. And, we discuss a theoretical analysis on the magnetic rotation of non-magnetic metal crystals by taking account of Lorenz force which acts in of molten metals.
