Abstract:
The present invention discloses a composite magnetic material. The composite magnetic material may comprise an Nd—Fe—B alloy and a Fe-based soft magnetic alloy having the general formula of Fe100-x-y-zAxRaSiyBz. A may be at least one element selected from Cu and Au. R may be at least one element selected from the group consisting of Ti, Zr, Hf, Mo, Nb, Ta, W and V. And the x, a, y, and z may satisfy: 0≦x≦3, 0≦a≦10, 0≦y≦20 and 2≦z≦25. The present invention further discloses a method of preparing the composite magnetic material as described above. According to the present invention, the composite magnetic material may have an enhanced magnetic energy product and residual magnetism respectively.
