New Phase Transitions in Perovskite Oxides: BiFeO3, SrSnO3, and Pb(Fe2/3W1/3)1/2Ti1/2O3

James F. Scott, +6 more
- 01 Jun 2008 - 
TL;DR: In this article, the authors report on two new aspects of oxide perovskites: the first part is devoted to new phase transitions, especially at high temperatures; multiferroics such as BiFeO3 and Pb-Fe-W-titanate are emphasized but nonmagnetic materials such as SrSnO3 are included.
