Barkhausen noise in the organic ferroelectric copolymer P(VDF:TrFE)
Barkhausen noise during polarization switching in P(VDF:TrFE) follows power-law size distributions with exponents that rise with applied field, fall with longer rise times, and approach the mean-field value of 1.5 for fast, strong driving.
