Magnetic Domain Wall Strip

In magnetism a domain wall is an interface separating magnetic domains.

Magnetic domain wall strip.

Abbreviated as dmi on the dynamics of the domain wall in a ferromagnetic strip. Martinez current driven domain wall dynamics in ferromagnetic layers synthetically exchange coupled by a spacer. It is a transition between different magnetic moments and usually undergoes an angular displacement of 90 or 180. Domain walls dws are nanometric spin arrangements between domains.

Here we provide a theoretical description of dw dynamics in fim strips based on an extended collective coordinates model 1dm. The boundary of the stripe domain region is composed of many tiny magnetic domain walls rather than a smooth domain wall. The period and magnetic layer thickness have obvious effect on the size of the stripe domain. A domain wall is a gradual reorientation of individual moments across a finite distance.

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. This may lead to a difference in the mechanism between the boundary expansion in our samples and domain wall motion in films without a stripe domain. Their structure and dynamics depend crucially on the local properties of the material and so they provide an invaluable probe to study nanomagnets.
