dc.description.abstractCrackling noise of ferroelectric lead zirconate titanate samples during ferroelectric switching is demonstrated to be compatible with avalanche statistics. The peaks of the slew rate (time derivative of current dI/dt squared), defined as "jerks," were statistically analyzed and shown to obey power laws. The critical exponent obtained is 1.64 ± 0.15, in agreement with predictions from avalanche theory. The exponent is independent of temperature within experimental error margins.
