Spinel ferrite [Ni0.2Co0.3Zn0.5Fe2O4] material has been synthesised for the use with Low Temperature Cofired Ceramic (LTCC) substrate material for embedded magnetic devices. Integration of such magnetic devices however, requires matching sintering temperatures of both materials. Considering the high sintering temperatures of ferrite materials compared to that of LTCC (≤900oC), this imposes the development glass-ferrite composites having requisite magnetic properties such as coercivity, saturation magnetization and remanent magnetization. The NiCoZn ferrite is synthesized by combustion synthesis method with neutral precursor solution. Structural and magnetic properties of the calcined ferrites were studied using vibrating sample magnetometer (VSM), respectively. The VSM result shows coercivity, saturation magnetization and remanent magnetization close to ~80 Oe, ~72 emu/g and ~5 emu/g respectively. Both properties promise as suitable for magnetic device applications. Experiments are carried out to optimize glass percentage and sintering temperature so as to achieve high densification of NiCoZn ferrite suitable for use in LTCC process. The ferrite material sintered with BBSZ glass shows relatively good sintered density (~85-90%) and electrical properties, permeability constant ~10 thus emphasizes use in LTCC based magnetic devices for high performance applications viz. fabrication of embedded inductors operating at RF frequencies
