Synthesis and characterization of NiCoMnCuFe1.96O4 for circulator application

► For the first time we successfully synthesized NiCoCuMn ferrites using microwave hydrothermal method. ► These samples were sintered at a low temperature of 950 °C for 45 min. ► Microwave properties were characterized by the out-of-plane and in-plane ferromagnetic resonance (FMR) measurements using a shorted waveguide. ► The obtained NiCoCuMn ferrites are used for the development of a new circulator in our Institute.
