逆向き磁化磁気構造体を生成する方法

Japanese Patent JP7189180

B2

A method of producing an oppositely magnetized magnetic structure within or on a substrate material includes: generating first and second numbers of cavities within or on a substrate material and filling the first and second numbers of cavities with first and second hard magnetic materials, respectively exhibiting first and second coercive field strengths, wherein the second coercive field strength is smaller than the first coercive field strength. The method further includes magnetizing, in a first direction, the first and second arrangements of magnetic structures, by a magnetic field having a field strength that exceeds the first and second coercive field strengths. The method further magnetizes the second arrangement of hard magnetic structures in a second direction, which differs from the first direction, by a second magnetic field having a field strength below the first coercive field strength but greater than the second coercive field strength.
