The M-type hexagonal ferrite thick films are prepared by tape casting . The morphology is investigated by scanning electron microscope (SEM), the phase composition is characterized by X-ray diffraction (XRD) and the magnetic properties are characterized by vibrating sample magnetometer (VSM). The result shows that thick film by tape casting has high remanence as 26.607emu/g, high magnetization as 55.236emu/g, high coercivity as 2323.8Oe, and high squareness ratio and a good morphology which is suitable for small and light-weight microwave and millimeter-wave devices . |
