Open Issues in Application Aspects of Domains in Ferroic Materials

摘要

Domain-related application aspects of ferroics are specified. Domains can play both positive and negative roles. Here we concentrate on the first aspect: using particular domain properties in practical devices. Several research areas related to these properties in single crystals are discussed in some detail, with the aim to specify some of the unsolved domain characteristics. The discussion is related to selected fields of applications and concerns various classes of domain engineering, writing domains, the effect of domain nucleation.
