Domains within domains and walls within walls: evidence for polar domains in cryogenic SrTiO3.
Resonant piezoelectric spectroscopy shows polar resonances in paraelectric SrTiO3 at temperatures below 80 K. These resonances become strong at T<40 K. The resonances are induced by weak electric fields and lead to standing mechanical waves in the sample. This piezoelectric response does not exist in paraelastic SrTiO3 nor at temperatures just below the ferroelastic phase transition. The inter...
متن کاملDomains, domain walls and the coercive field of amorphous ferromagnets
2014 Magnetic properties of the hysteresis loop of magnetostrictive amorphous ferromagnetic alloys are predominantly determined by the magnetoelastic coupling energy between the spontaneous magnetization and internal stresses. Domain structures as well as the pinning of domain walls are governed by long-range and shortrange stresses, respectively. As sources of elastic stresses we have detected...
متن کاملApplying Aspects within Modern Computing Domains
Aspect orientation is changing the way software is developed within various computing domains. In this paper we discuss the characteristics of aspect oriented programming, and the development of new or existing applications using aspect-oriented techniques and tools. We will show that this attractive technology is useful for solving the problems of code scattering and tangling within various co...
متن کاملWalking within growing domains: recurrence versus transience*
For normally reflected Brownian motion and for simple random walk on independently growing in time d-dimensional domains, d ≥ 3, we establish a sharp criterion for recurrence versus transience in terms of the growth rate.
متن کاملPolicy Iteration within Logico-Numerical Abstract Domains
Policy Iteration is an algorithm for the exact solving of optimization and game theory problems, formulated as equations on min max affine expressions. It has been shown that the problem of finding the least fixpoint of semantic equations on some abstract domains can be reduced to such optimization problems. This enables the use of Policy Iteration to solve such equations, instead of the tradit...
