It consists of a core with fast varying rotation, where the magnetization points are nearly orthogonal to the two domains, and two tails where the rotation logarithmically decays.
Néel walls are the common magnetic domain wall type in very thin films, where the exchange length is very large compared to the thickness..
Domain walls (DW)—very thin regions separating domains—play an essential role in the electrical, electromechanical, and optical properties of ferroelectrics.
For example, a high wall mobility promotes fast polarization switching of the material..
The domain walls are small regions where the direction of magnetization changes quite rapidly, from some particular direction in one domain to a different direction in an adjacent domain..
In string theory, a domain wall is a theoretical (d−1)-dimensional singularity.
A domain wall is meant to represent an object of codimension one embedded into space (a defect in space localized in one spatial dimension).
For example, D8-branes are domain walls in type II string theory..
In magnetism, a domain wall is an interface separating magnetic domains.
It is a transition between different magnetic moments and usually undergoes an angular displacement of 90\xb0 or 180\xb0.
A domain wall is a gradual reorientation of individual moments across a finite distance..
Domain walls are the boundaries between the regions (domains) in which all spins (or magnetic dipoles) are aligned in the direction of the easy axis.
At the domain wall magnetic dipoles or spins have to reorient themselves..
Domain walls (DWs) are the magnetic structures of finite width that separate regions of uniform magnetization in a magnetic material (the domains)..
Domain walls are interfaces between regions in which the magnetization has different directions.
Within the wall, the magnetization must change direction from that in one domain to that in the other domain.
Domain walls have a finite width that is determined principally by exchange and magnetocrystalline energy..
Unstable cosmic domain walls may decay and produce observable radiation.
There exist a class of the braneworld models where the brane is assumed to be a domain wall formed by interacting extra-dimensional fields. The matter is localized due to the interaction with this configuration and can leave it at sufficiently high energies.
Cosmological domain walls can be formed as a result of symmetry breaking at any epoch during the evolution of our universe.
We study their interaction with a classical macroscopic object, like Earth or a satellite in Earth's orbit.
Early in the universe, spontaneous breaking of discrete symmetries produced domain walls.
The resulting network of domain walls influenced the late stages of cosmological inflation and the cosmic microwave background radiation.
Observations constrain the existence of stable domain walls.
Scientists have witnessed domain walls before, but this is the first time that a team has developed a reliable way to create and study them.
The researchers simulated a Bose-Einstein condensate, a state of matter where the constituent particles are cooled to the point that they condense into a single quantum object.
