Structure and dielectric properties of Ba $_{2}$ Cu $_{x}$ Y $_{1 - x}$ TaO $_{6 - y}$ double perovskite

F. S. Oliveira, C. A. M. dos Santos, A. J. S. Machado +2

In this paper, we reported the effect of Cu doping on the structural and dielectric properties of Ba $_{2}$ Y $_{1 - x}$ Cu $_{x}$ TaO $_{6 - y}$ (0.00 $\leq$ x $\leq$ 0.50) ceramics at room temp…

Interplay between antiferrodistortive, ferroelectric and superconducting instabilities in Sr_{1-x}Ca_{x}$TiO_{3-δ}

B. S. de Lima, M. S. da Luz, F. S. Oliveira +11

SrTiO $_{3}$ undergoes a cubic-to-tetragonal phase transition at 105K. This antiferrodistortive transition is believed to be in competition with incipient ferroelectricity. Substitu…
