摘要：
Pulse polarizations of (Pb,La)(Zr,Ti)O-3 ferroelectric capacitor were measured from the switching current responses in the pulse width range from I mus to I s. Pulse width dependent polarizations are studied. In the case of all write/read pulse widths are same, switched polarization(P*) increased but non-switched polarization(P<^>) decreased with increasing pulse width. These results are explained by poling effects and confirmed by measuring pulse width dependencies with different patterns of pulse trains.
