Description of domain wall motions by the hyperbolic law
Abstract
In ferroelectric materials, domain walls interact with lattice defects and several types of domain walls displacements can be observed. When a domain wall is trapped at a pinning point, it can “jump” to another pinning center only if the driving electric field is sufficiently high. On the contrary, if the field is too weak, the domain wall only vibrates around its equilibrium position. Thus, both situations contribute to the value of the permittivity which can be described by the hyperbolic law. This law is based on reversible and irreversible domain wall motions and allows us to dissociate the domain wall and lattice contributions from the dielectric measurements.
