Magnetic Domain Wall Strip

The period and magnetic layer thickness have obvious effect on the size of the stripe domain.

Magnetic domain wall strip.

Its dynamic response to external factors such as applied magnetic fields or electrical currents depend heavily on the structure of the domain wall. B differential kerr images of magnetic domain wall displacement under a magnetic field of 2 6 mt and gate voltages of 1 0 and 0 8 v. 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 or 180. The project exploits the use of computer simulations to replicate a physical experiment.

The boundary of the stripe domain region expands just like a domain wall when it is driven by a magnetic field and the velocity follows the creep law which is consistent with typical domain walls. The repeat number and magnetic layer thickness have an obvious effect on the size of the stripe domain.

E field control of domain wall dynamics in cofeb. The resulting magnetic. 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 strips are made with a curved shape to easily set a domain wall in the bent region after the application of an external magnetic field transverse to the strip 27 28.

A domain wall is a gradual reorientation of individual moments across a finite distance. Martinez current driven domain wall dynamics in ferromagnetic layers synthetically exchange coupled by a spacer.

The domain wall was driven by an applied magnetic field.

On the dynamics of the domain wall in a ferromagnetic strip. The strip consists of two uniformly magnetized domains separated by a bloch wall. A micromagnetic study journal of applied physics 123 1. Adapted from lin et al.
