Popis:	We have constructed phase diagrams of Pb0.995La0.005[Zr0.95 − y Sn0.05 (Mg1/3Nb2/3) y ]0.99875O3 (y = 0–0.02) solid solutions in different electric fields. Our results demonstrate that, by cooling in a constant electric field, the low-temperature rhombohedral ferroelectric phase can be stabilized in a narrow temperature range. It is shown that the phase state below the Curie temperature strongly depends on the temperature-field history of the material. In particular, the low-temperature rhombohedral ferroelectric phase only appears during cooling. At the same time, the temperature-field stability region of the tetragonal antiferroelectric phase is much broader during heating.
