Three-dimensional alignment of FeSi2 with orthorhombic symmetry by an anisotropic magnetic field

Abstract

This paper presents the three-dimensional alignment of β-FeSi 2 particles in a resin under an anisotropic magnetic field. The alignments obtained under a static magnetic field and a rotating magnetic field proved that the magnetic susceptibilities of β-FeSi2 are χc>χb>χa. The magnetic anisotropy was sufficiently large under a magnetic field of 10T for the crystallographic alignment. Under an anisotropic magnetic field (oscillating magnetic field), a-, b- and c-axes of β-FeSi2 particles suspended in a resin were aligned each other. A pseudo single crystal β-FeSi2 with the orthorhombic structure was fabricated by the oscillating magnetic field. © 2009 IOP Publishing Ltd.
