Micromagnetic analysis of a magnetic domain wall in 2-d and 3-d nanocontacts
We have performed micromagnetic calculations of magnetic domain walls in two-dimensional (2-D) and three-dimensional (3-D) nanocontacts and estimate the domain wall widths. The magnetic domain wall in a 3-D nanocontact is smaller than that in a 2-D nanocontact due to the larger magnetic volume avail...

| description | We have performed micromagnetic calculations of magnetic domain walls in two-dimensional (2-D) and three-dimensional (3-D) nanocontacts and estimate the domain wall widths. The magnetic domain wall in a 3-D nanocontact is smaller than that in a 2-D nanocontact due to the larger magnetic volume available to pin the magnetization in the antiparallel configuration of the electrodes. Therefore, 3-D nanocontacts are more suitable than 2-D nanocontacts for domain wall confinement and large magnetoresistance effects. |
