Magnetic Domain Wall Strip

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.

Abbreviated as dmi on the dynamics of the domain wall in a ferromagnetic strip. 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. 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. 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. The period and magnetic layer thickness have obvious effect on the size of the stripe domain. A micromagnetic study journal of applied physics 123 1.

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.

Their structure and dynamics depend crucially on the local properties of the material and so they provide an invaluable probe to study nanomagnets.

However the conventional control methods e g epitaxial strain local heating magnetic field and magnetoelectric effect of the stripe ordered domain walls either cannot meet the demands for miniaturization and low power consumption of spintronic devices or require high strength of the electric field due to the small value of the magnetoelectric effect at room temperature.
