A schematic representation of the e field magnetic device incorporating a mgo tio2 composite dielectric barrier.
Its dynamic response to external factors such as applied magnetic fields or electrical currents depend heavily on the structure of the domain wall.
A domain wall is a gradual reorientation of individual moments across a finite distance.

The domain wall thickness depends on the anisotropy of the material but on average spans across around 100 150 atoms.
The repeat number and magnetic layer thickness have an obvious effect on the size of the stripe domain.

Here we provide a theoretical description of dw dynamics in fim strips based on an extended collective coordinates model 1dm.
The strip consists of two uniformly magnetized domains separated by a bloch wall.
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 period and magnetic layer thickness have obvious effect on the size of the stripe domain.
The boundary of the stripe domain region expand just like a domain wall when it is driven by magnetic field and the velocity follow the creep law which is consistent with the typical domain wall.
