MAGNETIC MATERIAL

摘要

Disclosed is a magnetic material comprising a crystal of µ-Ga x Fe 2-x O 3 (wherein 0 < x < 1) prepared by substituting a part of Ga 3+ ion sites of an µ-Fe 2 O 3 crystal with Ga 3+ ions and having X-ray diffraction peaks corresponding to the crystal structure of µ-Fe 2 O 3 . The coercive force of the magnetic material lowers in accordance with the Ga content thereof, and the saturation magnetization thereof has a maximum value.
