Low temperature sintering (Ni/Mn)CuZn ferrite was employed at most cases due to its co-firability with Ag (below 960 °C).The purpose of this study is to fabricate (Ni/Mn)CuZn ferrite sintered body with high-strength and high-frequency magnetic properties. Following is the procedure: firstly, (Ni/Mn)CuZn ferrite powder was synthesized under CO2 atmosphere at 500 °C from the mixed doxalate synthesized by co-precipitation method; then a small amount of boric acid [H3BO3] was added to the powder, and the (Ni/Mn)CuZn ferrite powder compact was prepared with Newton press and CIP methods; finally, (Ni/Mn)CuZn ferrite sintered body was fabricated by sintering at 900 °C under CO2 atmosphere. By this method, NiCuZn and MnCuZn ferrite sintered bodies with 0.5 mass% boric acid were obtained, the strength are 430 and 530 MPa respectively. The effect of various Mn addition on NiCuZn electromagnetic properties were studied.

Impregnation method was used for fabricating Co/YIG (Y3Fe5O12) composites under low temperature, and the electromagnetic properties were tuned by adjusting the content (0 wt% - 35 wt%) and microstructure of the metal in composites. The XRD and SEM were used to analyze the phase and microstructure. Electromagnetism properties including reactance, permittivity and permeability of the composites were tested using impedance analyzer (10 MHz~1 GHz). The results indicated that, the high cobalt content leads to the formation of three-dimensional cobalt networks on the pore walls of porous YIG gradually, and their electromagnetic properties have also been changed significantly with the Co content increasing. Especially, double negative properties were achieved in Co/YIG composites when the content of Co reached 35 wt% at the frequency band of 575 MHz-1 GHz. The appearance of double negative properties in cermets provides promising applications in electromagnetic stealth materials, microwave antenna, and traveling wave tubes.
