Paper Abstract

The design of multichannel data acquisition computer controlled setup for the pyroelectric measurement in a wide range of DC bias and ambient temperatures (280-350 K) under different conditions of pyroelectric currents is presented. The ceramic samples of 0.9 Pb Mg1/3Nb2/3O3 - 0.1 PbTiO3 (PMN-PT) solid solutions prepared in Ioffe Physico-Technical Institute were selected for measurements. The figures of merit of this ceramics calculated using the measured dielectric and pyroelectric data are presented in comparison with other pyroelectric materials and IR detectors.
