Relaxor-based ferroelectric single crystals xPb(In₁/₂)Nb₁/₂)O₃-yPb(Mg₁/₃Nb₂/₃)O₃-(1-x-y)PbTiO₃ {PIMNT [100x/100y/100(1-x-y)]} have been grown by a modified Bridgman technique. The as-grown PIMNT (42/30/28) crystal with rhombohedral perovskite-type structure shows higher Curie temperature TC ~ 187 °C, and higher ferroelectric rhombohedral-to-tetragonal phase transition temperature TRT ~ 152 °C, both about 50 °C higher than those found for 0.71Pb(In₁/₂)Nb₁/₂)O₃-0.3Pb(Mg₁/₃Nb₂/₃)O₃-0.29PbTiO₃ crystals. Moreover, as a core parameter of pyroelectric material, the detectivity figures-of-merit of PIMNT (42/30/28) crystal are higher than other typical relaxor-based ferroelectric crystals, which primarily stems from the lower dielectric loss, making it promising candidate for infrared detector applications.
