The anatomy of magnetic field pulse induced transverse domain wall dynamics [PDF]
Scientific ReportsThe microscopic anatomy of the precessional torque-induced magnetic domain wall racetrack memory is numerically investigated. A systematic analysis is performed to explain the efficiency and limitations of this domain wall motion architecture.

Spinor domain wall and test fermions on an arbitrary domain wall
European Physical Journal C: Particles and Fields, 2023 We consider a spinor domain wall embedded in a five-dimensional spacetime with a nondiagonal metric. The corresponding plane symmetric solutions for linear and nonlinear spinor fields with different parameters are obtained.

Frontiers in Physics, 2022 We develop a theory for the dynamics of a magnon on top of a domain wall in a ferromagnetic nanotube. Due to the geometry of the sample, domain walls are classified by the Skyrmion charge which counts the winding number of magnetic textures.
