Oxyhydrides of (Ca,Sr,Ba)TiO₃ Perovskite Solid Solutions

Inorganic Chemistry, 2012
The oxyhydride solid solutions (Ca,Sr)TiO(3-x)H(x) and (Sr,Ba)TiO(3-x)H(x) have been prepared by reducing the corresponding ATiO(3) oxides with calcium hydride. Under the reaction conditions examined, a hydride content of x = 0.1-0.3 was obtained for all compositions. Compared to our previous result with BaTiO(3-x)H(x), the larger particle size in this

Homogenization mechanism of perovskite solid solutions

Ferroelectrics, 1999
Abstract Mechanism of homogenization of perovskite solid solutions was studied. Compositional inhomogeneity (compositional fluctuation) of lead titanate zirconate (PZT) was found by a measurement of X-ray diffraction peaks. The compositional fluctuation was considered to be caused from a gap where neither mechanical mixing of raw materials nor ...

Investigations on magnetically diluted KNixMg1–xF3 perovskite solid solution

Physica Status Solidi (a), 1988
The magnetic properties and EPR spectra of magnetically diluted KNixMg1−xF3 perovskite solid solutions are examined. The susceptibility measurements show that these compounds are isotropic antiferromagnetic materials at high nickel concentrations. A critical concentration is found to be x = 0.4.

Atomic-level simulation of ferroelectricity in perovskite solid solutions

Applied Physics Letters, 2000
Building on the insights gained from electronic-structure calculations and from experience obtained with an earlier atomic-level method, we developed an atomic-level simulation approach based on the traditional Buckingham potential with shell model which correctly reproduces the ferroelectric phase behavior and dielectric and piezoelectric properties ...

Magnetic exchange interactions in perovskite solid solutions. Part 3. Tin-119 Mössbauer spectra of doped iron perovskite solid solutions

J. Chem. Soc., Dalton Trans., 1983
A detailed study has been made of supertransferred hyperfine field (s.t.h.f.) effects at 119Sn doped into various perovskites with the formula (A0.95Ca0.05)(Fe0.85M0.10Sn0.05)O3 with A = La, Eu, or Lu and M = Al, Ga, Sc, Cr, Mn, Co, or Ni. The observed s.t.h.f.

Quantum chemical modelling of polarons and perovskite solid solutions

Computational Materials Science, 2001
Abstract Following our previous study [J. Phys.: Condens. Matter 10 (1998) 6271] of a single Nb impurity and Nb clusters in KTaO 3 , we present results of the calculations for a series of perovskite KNb x Ta 1− x O 3 (KTN) solid solutions ( x =0, 0.125, 0.25, 0.75, 1).

Perovskite-like Solid Solutions in the System LiTaO3-CaZrO3

Journal of Solid State Chemistry, 1994
Abstract An investigation of the LiTaO 3 -CaZrO 3 phase diagram has been carried out and the solid solution limits redetermined. LiTaO 3 solid solutions extend from 0 to 20 mole% CaZrO 3 . CaZrO 3 solid solutions cover the range 27 to 100 mole% CaZrO 3 , but are incomplete since a two-phase region or immiscibility gap occurs over the range ∼ 88 to

Mössbauer Studies of BiFeO3-PbTiO3 Perovskite-Type Solid Solutions

Journal of Applied Physics, 1971
The Mössbauer spectra of the ferroelectric solid solutions (BiFeO3)x(PbTiO3)1−x have been studied as a function of temperature, mainly between room temperature and 600°C, using 57Fe in the solutions as an absorber. The quadrupole splitting increased and the isomer shift decreased between x=0.05 and x=0.70, a range in which the solutions are tetragonal ...
