Spin-orbit torque driven motion of chiral domain walls induced by radial magnetization in nanotube geometry
Nobuyuki Umetsu, Hiroki Tokuhira, Michael Quinsat +3
We theoretically investigate chiral domain walls (DWs) formed in radially magnetized nanotubes composed of ultrathin layers with perpendicular magnetic anisotropy (PMA). Unlike tho…

Spin orbit torque-driven motion of quasi-Bloch domain wall in perpendicularly magnetized W/CoFeB/MgO structure
Nobuyuki Umetsu, Michael Quinsat, Susumu Hashimoto +2
The motion of chiral magnetic domain walls (DWs) driven by spin-orbit torque (SOT) has been extensively studied in heavy metal/ferromagnet heterostructures with perpendicular magne…
