摘要：

The crystalline symmetry of the solid solution formed by a relaxor and a ferroelectric material with formula: (1-x)Pb(Fe2/3W1/3)O-3-xPbTiO(3), with various x was investigated, at T=300 K. A continuous change from pseudocubic to tetragonal symmetry, with cell parameters dependent on the PbTiO3 amount, was found. In a large range of compositions, from x=0.20 to x=0.37, both phases coexist, with different relative amounts. (C) 2002 American Institute of Physics.
