Polar phonons in some compressively stressed epitaxial and polycrystalline SrTiO3 thin films
D. Nuzhnyy, J. Petzelt, S. Kamba +5
Several SrTiO3 (STO) thin films without electrodes processed by pulsed laser deposition, of thicknesses down to 40 nm, were studied using infrared transmission and reflection spect…
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…
Nonvolatile ferroelectric control of ferromagnetism in (Ga,Mn)As
I. Stolichnov, S. W. E. Riester, H. J. Trodahl +7
There is currently much interest in materials and structures that provide coupled ferroelectric and ferromagnetic responses, with a long-term goal of developing new memories and sp…
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…
