Raman spectroscopy of (K,Na)NbO3 and ((K,Na)1-xLix)NbO3
H. J. Trodahl, N. Klein, D. Damjanovic +4
A Raman scattering spectroscopy study is reported through all four phases of a (K0.5Na0.5)NbO3 crystal and ((K0.5Na0.5)1-xLix)NbO3 for x=0.02 and 0.03. The transitions among the fe…
Hardening-softening transition in Fe-doped Pb(Zr,Ti)O3 ceramics and evolution of the third harmonic of the polarization response
Maxim I. Morozov, Dragan Damjanovic
It is shown that the phase angle of the third harmonic of polarization response (delta3) is very sensitive to the ageing state of hard, Fe-doped lead zirconate titanate [Pb(Zr,Ti)O…
Uniaxial-stress induced phase transitions in [001]c-poled 0.955Pb(Zn1/3Nb2/3)O3-0.045PbTiO3
P. -E. Janolin, M. Davis, B. Dkhil +2
First-order, rhombohedral to orthorhombic, stress-induced phase transitions have been evidenced by bulk charge-stress measurements and X-ray diffraction derived lattice strain meas…
Rotator and extender ferroelectrics: Importance of the shear coefficient to the piezoelectric properties of domain-engineered crystals and ceramics
Matthew Davis, Marko Budimir, Dragan Damjanovic +1
The importance of a high shear coefficient d15 (or d24) to the piezoelectric properties of domain-engineered and polycrystalline ferroelectrics is discussed. The extent of polariza…
Piezoelectric Response and Free Energy Instability in the Perovskite Crystals BaTiO3, PbTiO3 and Pb(Zr,Ti)O3
Marko Budimir, Dragan Damjanovic, Nava Setter
The question of the origin of the piezoelectric properties enhancement in perovskite ferroelectrics is approached by analyzing the Gibbs free energy of tetragonal BaTiO3, PbTiO3 an…
Anharmonicity of BaTiO_3 single crystals
Y. L. Wang, A. K. Tagantsev, D. Damjanovic +3
By analyzing the dielectric non-linearity with the Landau thermodynamic expansion, we find a simple and direct way to assess the importance of the eighth order term. Following this…
