Electrical Studies of Barkhausen Switching Noise in Ferroelectric lead zirconate titanate (PZT) and BaTiO3: Critical Exponents and Temperature-dependence

Abstract

Previous studies of Barkhausen noise in PZT have been limited to the energy spectrum (slew rate response voltages versus time), showing agreement with avalanche models; in barium titanate other exponents have been measured acoustically, but only at ambient temperatures. In the present study we report the Omori exponent (-0.95$\pm$0.03) for aftershocks in PZT and extend the barium titanate studies to a wider range of temperature.
