Temperature-induced isostructural phase transition, associated large negative volume expansion, and the existence of a critical point in the phase diagram of the multiferroic (1 - X)BiFeO3-xPbTiO3 solid solution system

Bhattacharjee, S.; Taji, K.; Moriyoshi, C.; Kuroiwa, Y.; Pandey, D. (2011-09-12)

We report here an unusual ferroelectric to ferroelectric isostructural phase transition and associated giant negative thermal expansion (NTE) for the tetragonal composition x = 0.31 closest to the morphotropic phase boundary ...
