Summary: | Some peculiar features of magnetic x,T-phase diagram of (1-x)PbFe sub(1/2)Nb sub(1/2)O sub(3)-xPbTiO sub(3) system at x approximately 0.1 have been ascribed previously to the change of the lattice symmetry from rhombohedral to tetragonal or to the decrease of the lattice parameter with x. We carried out structural, dielectric, magnetization, and Mossbauer studies of (1-x)PbFe sub(1/2)Nb sub(1/2)O sub(3)-xPbZrO sub(3) system, where the symmetry remains rhombohedral, while the lattice parameter increases with x. However, the magnetic x,T-phase diagram of (1-x)PbFe sub(1/2)Nb sub(1/2)O sub(3)-xPbZrO sub(3) appeared to be very similar to that of (1-x)PbFe sub(1/2)Nb sub(1/2)O sub(3)-xPbTiO sub(3). Anomalies of composition dependence of magnetic phase transition temperatures at x approximately 0.1 are supposed to be due to the percolation phase transition. |
