${\mathrm{BaTiO}}_{3}$ (BT) is the best-known ferroelectric and $\mathrm{Pb}{\mathrm{Mg}}_{1/3}{\mathrm{Nb}}_{2/3}{\mathrm{O}}_{3}$ (PMN) is the best-known relaxor ferroelectric, but their solid solutions were so far studied only very scarcely. Here

Water is characterized by large molecular electric dipole moments and strong interactions between molecules; however, hydrogen bonds screen the dipole–dipole coupling and suppress the ferroelectric order. The situation changes drastically when wate
