Study of phase transitions and properties of tetragonal (Pb, La) (Zr, Ti)O3 ceramics—III : Transitions induced by electric fields [PDF]

open access: yes, 1980
The phase diagram of electrically poled, tetragonal PLZT materials has been investigated. In the higher La concentration range, a tetragonal, so-called β-phase occurs, which has no clear FE properties.
