Fabrication and Magnetic Properties of LTCC NiZnCu ferrite thick films

Abstract

For appling low temperature co‐fired ceramics technology on NiZnCu ferrite with Ag electrode, the synthesis of nano‐sized NiZnCu ferrite powders using metal nitrates and the fabrication of ferrite thick films by a doctor blade method were carried out. Microstructural analysis confirmed that nano‐sized ferrite powders and fully densified thin films were successively fabricated. At a sintering temperature of 950 °C the magnetic properties of the ferrite thick film with 0.2–0.3 mol Cu were close to those of bulk materials (permeability >450, coercivity <3 Oe).
