Evaluation of magnetic susceptibility difference of coagulated particles for crystal alignment

International audience; Elicitation of crystallographic anisotropy is one of the promising methods for formation of functional materials because it enhances physical, chemical, mechanical and/or biological natures. Magnetic alignment is one of the powerful method of crystal alignment with magnetic susceptibility difference, in which operating parameters such as minimum intensity of the magnetic field and alignment time depend on the magnetic susceptibility difference. Thus, evaluation of the magnetic susceptibility difference of particles used as a raw material is essential for optimization of the crystal alignment process. However, it is different from that of a single crystal because particles used as a raw material is usually poly-crystals and/orcoagulated, and it might have distribution. In this paper, evaluation of distribution of the magnetic susceptibility difference of bismuth particles has been investigated.
