Dense Ni(0.37)Cu(0.20)Zn(0.43)Fe(1.92)O(3.88)/(Ba(0.6)Sr(0.4))TiO(3) composite thick films were prepared through screen printing method and sintered at 880 degrees C. The powder XRD patterns confirm the coexistence of the two phases. The dielectric and magnetic properties are also reported. The results show that this kind of magnetic-dielectric composite thick films, possessing high permittivity and saturation magnetization, moderate dielectric tunability, and very low dielectric loss and coercivity, could be used in high-frequency communications for the capacitor-inductor integrating devices such as electromagnetic interference filters and antennas.
