Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Based on the direct domain observations in the Rochelle salt crystals, the
final stages of polarization and the dependence of polarized state stability
on the electric field strength E and on the electric pulse duration is
investigated.
The conclusion is made that there exists a high electric field strength, at
which small domains are displaced. At higher fields, electrooptical effects
are obviously developed and the invisible network of defects is changed.
The stability of the polarized state and the degree of polarization are determined
by the electric field pulse, the duration τ and the electric strength
of which E are connected by equation ln τ ∼ k/E + b . For incomplete
polarization, the rate of polarization decay when the pulse is finished is
proportional to the deviation of the domains from the initial state of the
sample. |
