Effect of La doping on the ferroic order in Pb-based perovskite-type relaxor ferroelectrics
(American Physical Society, 2011-04-07)
The structural alteration induced by the substitution of three-valent cations with an isotropic electronic outermost shell for Pb2+ in perovskite-type relaxors was investigated in the solid solutions Pb1-xLaxSc(1+x)/2Ta(1-x)/2O3, ...
Structural state of relaxor ferroelectrics PbSc0.5Ta0.5O3 and PbSc0.5Nb0.5O3 at high pressures up to 30 GPa
(American Physical Society, 2011-11-07)
The pressure-induced structural changes in perovskite-type (ABO(3)) Pb-based relaxor ferroelectrics are studied on the basis of in situ single-crystal synchrotron x-ray diffraction and Raman scattering experiments on ...
Lagrangian and energy forms for retrieving the impulse response of the Earth due to random electromagnetic forcing
(American Physical Society, 2011-08-10)
We distinguish between trivial and nontrivial differences in retrieving the real or imaginary parts of the Green's function. Trivial differences come from different Green's function definitions. The energy and Lagrangian ...
Comparison between beryllium and diamond-backing plates in diamond-anvil cells: Application to single-crystal x-ray diffraction high-pressure data
(AIP Publishing, 2011-05)
A direct comparison between two complete intensity datasets, collected on the same sample loaded in two identical diamond-anvil pressure cells equipped, respectively, with beryllium and diamond-backing plates was performed. ...
