Abstract :
Magnetic nanophase cobalt ferrite particles were synthesized through a water-based method. The obtained nanoparticles were characterized by x-ray diffraction (XRD), transmission electronic microscopy (TEM), and superconducting quantum interference device (SQUID) magnetometer. Magnetic nanocomposite was prepared by mixing the nanoparticle with epoxy/anhydride matrix. The dielectric and magnetic properties of the composite were measured by LCR meter and SQUID magnetometer. The design and fabrication of embedded inductor for Network Analyzer measurement is under an ongoing process.
