The complete set of material parameters of a top-seeded solution-grown BaTiO 3 crystal has
been determined by numerically evaluating available measurements and using additional …

The possibilities of vacancy-induced magnetism in perovskite BaTiO3 are investigated by
first-principles calculations. Calculated results show that both titanium and oxygen …

We performed ab initio calculations on the magnetism of Na 0.5 Bi 0.5 TiO 3 (NBT) with
rhombohedral perovskite structure. Calculated results show that an ideal NBT is non …

We numerically solve charge-transport and Poisson equations for photorefractive BaTiO_3
single crystals with a band model, using four impurity levels, Fe^ 2+–Fe^ 3+, Fe^ 3+–Fe^ 4+ …

The microscopic mechanism of electro-optic effect in tetragonal phase of monodomain pure
and Fe doped barium titanate crystals is discussed taking account of the piezoelectric effect …

The microscopic mechanism of electro-optic effect in tetragonal phase of BaTiO3 is
discussed taking account of the piezoelectric effect due to the lattice deformation and the …

Both oxygen deficiency and excess are possible in pure and doped barium titanate and do
influence in a passive or active manner its properties. Their crystal engineering by gas …

The microscopic mechanism of optical anisotropy in the tetragonal phase of BaTiO3 is
discussed taking account of the dipole-dipole effect due to the ionic and electronic …

Lead barium niobate is a new photorefractive material of high interest for a variety of
applications including holographic storage. Pb0. 5Ba0. 5Nb2O6 crystals have been grown …

The factors limiting the efficiency of Er3+ luminescence at 1.54 μm (0.8 eV) in erbiumdoped
barium titanate films were studied. To investigate the effect of film stoichiometry on …
