Soft magnetic composite with two-dimensional magnetic moment and high working frequency band, and preparation method therefor

A soft magnetic composite with a two-dimensional magnetic moment, comprising:

• an insulating matrix;
• and
• two-dimensional magnetic moment micropowder dispersed in the insulating matrix,
• wherein inside the two-dimensional magnetic moment micropowder, magnetic moments are isotropically distributed in specific two-dimensional planes in the two dimensional magnetic moment micropowder,
• wherein when an external operating magnetic field is zero, the magnetic moments of the two-dimensional magnetic moment micropowder are distributed in the specific two-dimensional planes in the two-dimensional magnetic moment micropowder, when the external operating magnetic field is not zero, the magnetic moment makes a rotation or precession motion in or along the specific two-dimensional planes under an action of the external operating magnetic field;
• wherein the two-dimensional magnetic moment micropowder dispersed in the insulating matrix is orientated by a multi-pole external orientation magnetic field or a rotating eternal orientation magnetic field to enable easy magnetization planes of the two-dimensional magnetic moment micropowder in the soft magnetic composite to be distributed in two-dimensional planes determined by the multi-pole external orientation magnetic field or the rotating external orientation magnetic field and a plane orientation degree of the soft magnetic composite is superior over 95%.
