Wetting of the ferroelectric domain walls is studied in external magnetic fields and for composition changes in (Ba, Sr)TiO3and Pb(Zr, Ti)O3. We discuss the sensibility of a domain structure to concentration of alloying element in perovskite ferroelectrics. A considerable magnetic-field- and concentration-induced variation of the ferroelectric domain size and the paraelectric layer width is demonstrated. The concentration-temperature “phase diagram” showing the range of the wetting existence is calculated.
