Abstract
Large ferroelectric single crystals of 0.48 Pb(Fe1/2Nb1/2)O-3-0.52 PbTiO3 s olid solution system were first successfully grown using a modified Bridgma n technique and their properties were investigated. The obtained crystals w ere about 25 mm in diameter, 100 mm in length and black in color. The cryst al exhibited abnormal dielectric properties that the dielectric constant wa s as high as 30000 and the dielectric loss factor was about 0.5 at room tem perature. The mechanism of this phenomenon was discussed.
