The first successful growth of La 1/2 Na 1/2 TiO 3 (LNTO) single crystals by floating zone method is reported. This growth requires specific atmosphere conditions to avoid vaporization of Na, and a post-growth annealing under dioxygen to get pure LNT

Publikováno v: Solid State Communications. 151:256-258

The valence band electronic structure of the Bi1−xPbxFeO3 (x=0.02–0.15) system which undergoes a R3c to cubic phase transition with Pb doping has been studied by using X-ray and ultra-violet photoelectron spectroscopy. The cubic composition showe

Ferroelectric order stability in theBi1−xPbxFeO3solid solution

Autor: Raphael Haumont, Jean Michel Kiat, J. Chaigneau

Publikováno v: Physical Review B. 80

Ferroelectric properties of ${\text{Bi}}_{1\ensuremath{-}x}{\text{Pb}}_{x}{\text{FeO}}_{3}$, through a structural approach, by structural Rietveld refinement and x-ray diffraction versus temperature have been carried out. This study allows us to draw

Morphotropic phase boundaries in(BiScO3)1−x(PbTiO3)x(0.60

Autor: Christine Bogicevic, Jean Michel Kiat, J. Chaigneau, Charlotte Malibert

Publikováno v: Physical Review B. 76

We have performed a structural study of the morphotropic phase boundary system $(1\ensuremath{-}x)\mathrm{Bi}\mathrm{Sc}{\mathrm{O}}_{3\ensuremath{-}x}\mathrm{Pb}\mathrm{Ti}{\mathrm{O}}_{3}$ in which both $A$ and $B$ sites of the perovskite are rando
