Abstract
Quantum ferroelectric and ferroelectric relaxor behavior has been found in For the quantum ferroelectric relationship holds with and obvious hysteresis loops were observed. The polarization relaxation shows critical slowing down. At high Bi concentration, a crossover from quantum ferroelectric to relaxor behavior occurred. The coexistence of ferroelectric and relaxor behavior in was attributed to a ferroelectric domain state induced by random fields.
