SPIN TEXTURES




We report a theoretical overview of the magnetic domain wall behavior under an electric current in infinitely long nanotubes with azimuthal magnetization. We highlight effects that, besides spin-transfer torques already largely understood in flat strips, arise specifically in the tubular geometry: the Œrsted field and curvature-induced magnetic anisotropy resulting both from the exchange interaction and […]

Magnetic spintronic memory called STT-MRAM have recently entered in volume production at major microelectronic foundries. The research in this area is now focused on preparing the future memory generations with higher capacity, higher speed, lower power consumption, wider range of operating temperature. To conduct this type of research, it is important to be able to […]

Magnetic skyrmions are topologically protected spin textures of great interest for nanoscale information storage and processing. However, stabilizing small skyrmions without applying an external magnetic field remains challenging. This study employs a thin ferromagnetic layer exchange-biased by an antiferromagnetic film to stabilize ferromagnetic skyrmions down to 30 nm in diameter, at zero magnetic field. In […]

Topological insulators (TI) represent a new class of insulating materials hosting metallic surface states. Moreover, those surface states exhibit a Dirac cone energy dispersion where the strong spin-orbit coupling leads to a helical spin texture at the Fermi level. This property can be exploited to detect spin currents in conventional semiconductors like silicon or germanium. […]

Domain-wall motion in one-dimensional conduits is both a textbook case for magnetization dynamics and the understanding of spin torques, and of practical importance for the design of novel spintronic ICT devices. However, instabilities known as Walker breakdown limit the speed in most cases. We have shown experimentally and confirmed by simulation, that these instabilities are […]
