METHOD OF INTRODUCING MAGNETIC ANISOTROPY INTO MAGNETIC MATERIAL

摘要

There is disclosed a method of introducing magnetic anisotropy into a magnetic material (12a, 12b), in which a laser beam (52) is selectively radiated on the surface of a magnetic material (12a, 12b) to locally heat it, thereby forming a pattern of boundary phases (14) for magnetically dividing a main phase (13) of the magnetic material (12a, 12b) into a plurality of regions, and magnetic domains of the divided main phase regions (13) are controlled to induce magnetic anisotropy in the main phase regions (13).
