| Popis: |
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 [Formula: see text] 0.03) for aftershocks in PZT and extend the barium titanate studies to a wider range of temperature. |
