Abstract:

In materials science, crystal growth technology is indispensable to maximize functionalities of materials. A practical method is the epitaxial growth technique such as melt-solidification using seed crystals and thin film growth on single-crystalline templates.
Our group focuses on tri-axial grain-orientation using by a modulated rotating magnetic field (MRF)[1,2] as a room-temperature process. Recently, equipment that can generate a linear drive type of MRF [3] applicable to a continuous production process was developed. It can generate a kind of MRF by reciprocating an arrayed permanent magnet unit. The unit has two different portions of bending magnetic field and uniform magnetic field, and can generate MRF with static and rotating magnetic fields with 0.9 T. In this presentation, tri-axial (or biaxial) alignment of orthorhombic cuprate superconductor powders and simulation research on the design of the magnet arrays will be reported.
