Description

Ceramic composites (x Ni0.15Cu0.3Zn0.55Fe2O4 + (1-x) BaTiO3) were prepared by a conventional ceramic method. X-ray diffraction (XRD) and electron probe micro analysis (EPMA) measurements were performed for these samples and it is confirmed that the composites consist of spinel ferrite and BaTiO3 phases. The composites are so homogeneous that the ferrite and BaTiO3 grains do not react to each other and have radii of 1-5 um. The resonant frequency in initial permeability and permittivity is increased by increasing the amount of BaTiO3. (author)
