Interface engineered perpendicular magnetic anisotropy-controlled propagation of magnetic domain

We report the impact of ferromagnetic layer thickness and stack configuration on the magnetic properties, perpendicular magnetic anisotropy (PMA), modified magnetization switching mechanisms, and creep regime domain wall (DW) dynamics, including their propagation velocity, in a P...

Multiscale Symmetry Breaking Enables Tunable Magnetic Anisotropy and Damping in Co 2 FeAl Thin Films

ABSTRACT The ability to simultaneously engineer magnetic stability and spin dissipation remains difficult to realize in scalable metallic thin films. Here, we show that multiscale symmetry breaking provides a route to achieve this control in polycrystalline Co 2 FeAl films withou...

Impact of He+ ion irradiation on the domain wall dynamics in Pd/Co/Pd trilayers with perpendicular magnetic anisotropy

Heavy metal/ferromagnetic-based heterostructures with perpendicular magnetic anisotropy (PMA) are prototypes for domain wall (DW)-based spintronic devices. We explored the impact of He + ion irradiation on the bubble DW dynamics in Pd/Co/Pd trilayers with PMA. The effective magne...
