Abstract :
PMN-PT with a PT content of 26%, 30%, and 38% respectively, was evaluated as a candidate for high performance detectors. Pyroelectric and dielectric measurements confirmed the extraordinary pyroelectric coefficient of about 1090 muC/m2/K and very low dielectric losses of about 0.0005 at 1 kHz of Mn doped PMN-26PT. The evaluation of PMN-PT based detectors also shows that (111) oriented Mn-doped PMN-PT with a PT content of 26-30 % is well suited as material for pyroelectric detectors. A specific detectivity D*(10 Hz, 500 K, 25degC) of 1.07middot109 cm/Hz1/2/W was obtained.
