Dielectric investigations of the (PMN)(1-x)(PT)x crystalline solution have been performed for various electrical histories. For x<0.3, relaxor behavior was observed, however the degree of diffuseness in the dielectric maximum and degree of relaxor characteristics were decreased with increasing x. Application of dc bias for x<0.33 (xc) resulted in an induced transformation to a long-range ferroelectric state. This transition had a critical threshold field (Eth). The value of Eth depended on x. For all x<xc, glasslike behavior was observed in the nonergodic temperature range for E<Eth.
