Phase transformations of Pb0.995La0.005[Zr0.95 − y Sn0.05(Mg1/3Nb2/3) y ]0.99875O3 solid solutions

Effect of complex heterovalent doping on temperature and phase transformations in Pb1 − p La p [Zn0.9Mg(0.1 + p)/3Nb(0.2 − p)/3]O3 Solid Solutions

“…With additional cooling below room temperature, the samples with low lanthanum contents exhibited dielectric anoma lies accompanied by a minor decrease in spontaneous polarization. These results, together with the above structural data and the data reported in [8,9], allow us to state that at р 0.075 below Т С , two rhombohedral FE phases with the sp. gr.…”

“…Our choice of the basic material was based on several considerations: As is well known, the morphotropic interface between the AFE(O) and rhombohedral FE HT phases in the (1 -x)PbZrO 3 -xPb(Mg 1/3 Nb 2/3 )O 3 lead zircon ate-magnoniobate binary system corresponds to a composition with х ≈ 0.08-0.09 at room temperature [8,9]. Consequently, the chosen composition should correspond to the FE phase.…”
