    Notes: In this paper, lead hafnate titanate (PHT) was derived by chemical solution deposition (CSD) and characterized as a thin film material. The thin films were tested for the usage as a ferroelectric thin film in view of Ferroelectric Random Access Memory (FRAM) devices and compared with an equivalent lead zirconate titanate (PZT) thin film, which was prepared under the same conditions. After determining the thickness and the morphology of the PHT films, electronic measurements were performed to investigate this material as a promising candidate in view of FRAM applications due to failure mechanisms like fatigue and imprint.

    Notes: The aging behavior of the solid-solution series (Pb(Mg1/3Nb2/3)O3)1−x–(PbTiO3)x (PMN1−x−PTx) prepared by chemical-solution deposition without seeding layers was investigated. A strong influence of the rapid thermal annealing step on the film density was determined. The best nucleation and density of the thin films occurred when each deposited layer was separately pyrolyzed and crystallized. The thin-film microstructure was investigated using scanning electron microscopy. Conventional capacitance-voltage and hysteresis measurements were performed. For the first time, investigations on the fatigue performance and the leakage current for alternating-current and direct-current voltage were executed, which are important for the reliability in device applications.

    Notes: The purpose of the present investigation is to describe the influence of the processing parameters on the dielectric behavior of manganese-doped Ba(Ti1−xZrx)O3ceramics, particularly variations in the small-signal aging rate, temperature characteristic, and hysteresis. In this paper, the aging behavior of base-metal electrode materials above the temperature of the permittivity maximum (TM), including the influence of the zirconium content and annealing conditions, is described for the first time. The aging rate at temperatures greater than TM decreases as the oxygen partial pressure increases during annealing and the zirconium content increases, whereas the aging rate exhibits a maximum at temperatures much less than TM. The behavior is explained in terms of a diffuse phase transition. Hysteresis-loop deformation is observed during aging.
