Magnetic Domain Wall Wiki

The study of magnetic domains is called micromagnetics.

Magnetic domain wall wiki. A magnetic domain wall the boundary region between two magnetic domains with different magnetization orientations with nanoscale confinement can be considered as a particle trapped in a pinning potential well. The regions separating magnetic domains are called domain walls where the magnetization rotates coherently from the direction in one domain to that in the next domain. In particular a submicrometer planar nanowire made from a soft magnetic material such as permalloy ni 80. Its dynamic response to external factors such as applied magnetic fields or electrical currents depend heavily on the structure of the domain wall.

Electric currents and the magnetic moments of elementary particles give rise to a magnetic field which acts on other currents and magnetic moments. It is a transition between different magnetic moments and usually undergoes an angular displacement of 90 or 180. A domain wall is a gradual reorientation of individual moments across a finite distance. When the magnetization reverses by domain wall motion the net magnetization is small in every vector direction because the moments of all the individual domains sum to zero.

Magnetism is a class of physical phenomena that are mediated by magnetic fields.

Racetrack memory or domain wall memory dwm is an experimental non volatile memory device under development at ibm s almaden research center by a team led by physicist stuart parkin.

A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken.
