Results of the study of phase transitions in the system of solid solut
ions Pb-1-x(Li1/2La1/2)(x) (Zr1-yTiy)O-3 (PLLZT) at x = 0, 1 under the
effect of an electric field are presented. It is shown that there are
three regions of Ti-concentration on the ''composition-temperature''
phase diagram. The region of Ti-content fro m similar to 12 to similar
to 19% is the most interesting. In this region the succession of phas
e transitions depends on the prehistory of the specimens: in the absen
ce of an external electric field only the AFE-PE transition takes plac
e, but after the action of the field, the succession of phase transiti
ons FE-AFE-PE arises. Full ''temperature-field'' phase diagrams are co
nstructed.
