Unprecedented phase transition sequence in the perovskite Li(0.2)Na(0.8)NbO(3)

The perovskite Li(0.2)Na(0.8)NbO(3) is shown, by powder neutron diffraction, to display a unique sequence of phase transitions at elevated temperature. The ambient temperature polar phase (rhombohedral, space group R3c) transforms via a first-order transition to a polar tetragonal phase (space group...
