Supermagnetic material

Study period:1991 - 1993
Research overview:
This project aimed to develop materials for a superpowerful magnet and materials that markedly shrink and stretch when magnetic fields are applied (giant-magnetostriction). We elucidated the reaction characteristics and mechanisms of the intermetallic compounds with nitrogen, carbon, and boron, and obtained a new nitride for a superpowerful magnet. We also prepared giant-magnetostrictive thin films using the ion beam sputtering process which led to a pilot study of M-SAM (magnetic-surface acoustic wave) devices. New superpowerful magnets may be used for fuel-control actuators and dynamos under high temperatures in automobiles, and giant-magnetostrictive materials may be used for powerful sonars in deep-sea investigation, damping actuators for earthquakes, microactuators, etc. We believe that these results will contribute to growth in precision machinery, microsysytem technology, and similar industries.
