Effective pinning energy landscape perturbations for propagating magnetic domain walls (2016)
Journal Article
Burn, D., & Atkinson, D. (2016). Effective pinning energy landscape perturbations for propagating magnetic domain walls. Scientific Reports, 6, Article 34517. https://doi.org/10.1038/srep34517

The interaction between a magnetic domain wall and a pinning site is explored in a planar nanowire using micromagnetics to reveal perturbations of the pinning energetics for propagating domain walls. Numerical simulations in the high damping ’quasi-s... Read More about Effective pinning energy landscape perturbations for propagating magnetic domain walls.

Controlling the stability of both the structure and velocity of domain walls in magnetic nanowires (2016)
Journal Article
Brandão, J., & Atkinson, D. (2016). Controlling the stability of both the structure and velocity of domain walls in magnetic nanowires. Applied Physics Letters, 109(6), Article 062405. https://doi.org/10.1063/1.4960201

For magnetic nanowire devices, the precise control of both domain wall (DW) motion and pinning behaviour is essential for reliable functional performance. The domain wall velocity and wall structure are typically sensitive to the driving field or spi...

Evolution of damping in ferromagnetic/nonmagnetic thin film bilayers as a function of nonmagnetic layer thickness (2016)
Journal Article
Azzawi, S., Ganguly, A., Tokaç, M., Rowan-Robinson, R., Sinha, J., Hindmarch, A., …Atkinson, D. (2016). Evolution of damping in ferromagnetic/nonmagnetic thin film bilayers as a function of nonmagnetic layer thickness. Physical Review B, 93(5), Article 054402. https://doi.org/10.1103/physrevb.93.054402

The evolution of damping in Co/Pt, Co/Au, and Ni81Fe19/Pt bilayers was studied with increasing nonmagnetic (NM) heavy-metal layer thicknesses in the range 0.2nm≤tNM≤10nm, where tNM is the NM layer thickness. Magnetization precession was measured in t... Read More about Evolution of damping in ferromagnetic/nonmagnetic thin film bilayers as a function of nonmagnetic layer thickness.
