As a lead-free piezoelectric material, (K,Na)(Nb,Ta)O
3(KNNT) ceramics were synthesized by the solid state reaction method. Although KNNT ceramics were sintered by hot pressing due to the difficulty in normal sintering, the sinterability of this ceramics was greatly improved by the sintering aid ((K

29). With the increase of sintering aids, dielectric constant and Curie point changed lineally. This result means that a part of KCN or KCT react with KNNT and form a solid solution with KNNT. In addition, in order to improve the temperature properties, Li substitution for A site ions was investigated. 4 mol% Li substituted sample showed 50C higher Curie point than pure KNN ceramics.

We studied the frequency dispersion of complex permeability of polycrystalline Li-Zn ferrite and clarified that the ferrite has relatively large Snoek's product in spinel ferrites. It was also found that high resistivity was attained by a partial substitution of Fe with Mn. Additionally, the solid solution formation with Cu-ferrite enabled us to obtain the densification at low sintering temperature. In this study, we report the experimental results about the fabrication of multi-layer chip coil using Li-Cu-Zn ferrite and its impedance spectra.

Recently, research to examine the effect of coupling between ferroelectricity and ferromagnetism is just started for materials with both ferroelectric and ferromagnetic properties such as (Pb,La)(Zr,Ti)O3-BiFeO3, Bi6Ti3Fe2O18 and YMnO3. We are expecting to induce the coupling phenomenon by "orthogonalization" of spontaneous polarization and magnetization. On the basis of this concept, we prepared BaTiO3/(Ni,Zn)Fe2O4 epitaxial films in which spontaneous polarization and magnetization is orthogonalized. We also prepared BaTiO3/BaFe12O19 epitaxial films in which spontaneous polarization and magnetization is in parallel. To clarify the effect of "orthogonalization", electrical and magnetic properties were measured.

We successfully deposited the c-axis oriented PZT thin films with different compositions by inserting the c-axis oriented PZT seeding layer, which was deposited by the electric-field-assisted annealing (EFA-A), between the electrode and PZT precursor films derived from molecular-designed precursor solutions with different compositions. The electrical properties for the resulting PZT thin films were investigated to show the relation between the orientations and electrical properties. As a result, electrical properties, especially, the piezoelectricity exhibited the large dependence on the film orientation. PZT thin films with c-axis orientation showed higher piezoelectricity than those for the films with (001)&(100)-orientation.
