The dielectric response of [110]-oriented 0.68PMN-0.32PT single crystal under dc electric field has been investigated. The characteristics of phase transition under temperature and dc electric field are provided. When electric field is above 2.3kV/cm, abnormal phase transition is induced by temperature and electric field, which corresponds to the phase transition from rhombohedral to orthorhombic ferroelectric phase. With increasing dc electric field, the stable temperature region of orthorhombic phase is expanded. The electric field-temperature (E-T) phase diagram of [110]-oriented 0.68PMN-0.32PT single crystals is presented. The polarization rotation in [110]-oriented single crystal is discussed.

The crystalline electric field parameters Anmfor HoFe11Ti under different pressures were evaluated by fitting calculations to the magnetization curves measured on the single crystals at several temperatures. It was found that magneto-crystalline anisotropy has been changed by high pressure and the Anmfor HoFe11Ti under high pressures are strikingly different from Anmfor the corresponding HoFe11Ti H with interstitial hydrogen atom.

Direction Of Polarization

To induce fine engineered domain configurations into potassium niobate (KNbO3) single crystals, two kinds of methods were performed, i.e., (1) high DC electric field exposure along the opposite direction of polarization of KNbO3 single-domain crystals at room temperature, and (2) introduction of randomly oriented fine domain configuration by heat treatment at 700 °C and then high DC electric field exposure along [001]c direction of KNbO3 multidomain crystals at room temperature. When the method (1) was performed, finally, the poled KNbO3 crystals became to single-domain state again through the formation of multidomain state. On the other hand, the KNbO3 multidomain crystals were obtained by using the method (2), and an enhancement of piezoelectric-related properties was observed.

Results of measurements of independent piezoelectric moduli d 11 and d 14 in Ca3NbGa3Si2O14, La3Ga5.5Ta0.5O14 and La3Ga5SiO14, promising single crystals of the calcium gallogermanate structural type, are presented. The moduli were measured with a triple-axis X-ray diffractometer under an external electric field which causes changes in the interplanar distances due to the reverse piezoelectric effect. The results of the X-ray diffractometry measurements agree fairly well (within less than 10%) with the results obtained by different methods.
