First principles investigation of the strain-mode coupling in srbi2nb2o9

Urko Petralanda, I. Etxebarria

The Aurivillius compounds SrBi2Nb2O9 (SBN) and SrBi2Ta2O9 (SBT) present at room temperature isomorphous ferroelectric structures that are stabilized by a complex interplay of three…

Structural instabilities and sequence of phase transitions in SrBi $_{2}$ Ta $_{2}$ O $_{9}$ and SrBi $_{2}$ Nb $_{2}$ O $_{9}$ from first principles and Monte Carlo simulations

Urko Petralanda, I. Etxebarria

Despite their structural similarities, SrBi $_{2}$ Ta $_{2}$ O $_{9}$ (SBT) and SrBi $_{2}$ Nb $_{2}$ O $_{9}$ (SBN) undergo a different sequence of phase transitions. The phase diagram of SBT as a func…
