概要

Ceramic composites (x Ni_<0.15>Cu_<0.3>Zn_<0.55>Fe_2O_4 + (1-x) BaTiO_3) 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 BaTiO_3 phases. The composites are so homogeneous that the ferrite and BaTiO_3 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 BaTiO_3.
