The electron paramagnetic resonance parameters (g factors g‖,g⊥ and hyperfine structure constants A‖,A⊥) of PbTiO3: Cu 2+ are calculated from the complete diagonalization method and the perturbation theory method. The calculated results obtained by the complete diagonalization method are close to that obtained by the perturbation theory method, and in good agreement with the experimental values...

An x-ray-diffraction method that directly senses the phase of the structure factor is demonstrated and used for determining the local polarity of thin ferroelectric films. This method is based on the excitation of an x-ray standing-wave field inside the film as a result of the interference between the strong incident x-ray wave and the weak kinematically Bragg-diffracted x-ray wave from the fil...

We reported the non-volatile electric field-mediated magnetic properties in the half-metallic Heusler alloy Co2FeAl/Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure at room temperature. The remanent magnetization with different applied electric field along [100] and [01-1] directions was achieved, which showed the non-volatile remanent magnetization driven by an electric field. The two giant reversible ...

Thin films of FLZT with PbTiO3 interlayers have been fabricated by using a sol-gel spin-on process. Three compositions of PLZT, namely 8/65/35,15/40/60 and 18/30/70, have been deposited on platinum and quartz substrates and heat treated at 650°C. All three compositions have crystallized in the perovskite phase. The 8/65/35 composition, which has been investigated in greater detail exhibits a lo...

Numerous investigations on the development of relaxor-PbTiO3 ferroelectric crystals have been carried out since their extraordinary properties were revealed. Recent developments these offered further advances in electromechanical applications. In this review, recent and practical applications are reviewed. The single crystal growth methods first discussed. Two different strategies, poling dopin...
