What can we learn about ferroelectrics using methods of nonlinear dynamics?
The nonlinear series resonance circuit with ferroelectric capacitor has been extensively investigated. If the ferroelectric within the capacitor is in its polar phase many of the features well known from model systems of nonlinear dynamics may be observed. These characteristics are the shift of r...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The nonlinear series resonance circuit with ferroelectric capacitor has been
extensively investigated. If the ferroelectric within the capacitor is in its polar
phase many of the features well known from model systems of nonlinear
dynamics may be observed. These characteristics are the shift of resonance
frequency with increasing driving voltage, bifurcations and chaotic
behaviour. Considerations of the system on the basis of simple Landautheory
suggest to describe the resonance circuit by means of a Duffingequation.
Because of the switching process during the nonlinear vibrations
the real situation is more complicated as can be shown by nonlinear time
series analysis [1]. |
