The invention belongs to the field of soft magnetic ferrite materials, and in particular, relates to a NiCuZn soft magnetic ferrite material used for low temperature co-sintering. The material comprises major constituents and accessory constituents, wherein: the major constituents consist of ferric oxide, nickel oxide, zinc oxide and copper oxide, the molar percentage content of each major constituent being Fe2O3 45.5-48.5 mol%, NiO 16.5-19.5 mol%, ZnO 28.0-30.5 mol% and CuO 6.0-8.0 mol%; the accessory constituents comprise manganic oxide and bismuth oxide, compared with the gross weight of the major constituents, the weight percentage gross of the accessory constituents being 1.1-3.5 wt% calculated by taking MnO and Bi2O3 as standard. The invention also provides a preparation method for the ferrite material. When used for preparing MLCI devices under high frequency usage, the material of the invention has advantages in that: the material has a relatively low sintering temperature and metallic silver is not easy to diffuse during co-sintering; and the material ensures that the MLCI devices can obtain excellent magnetic properties and have a relatively good consistency.
