Electroless plating to produce flux-closure nanotube for three-dimensional spintronics building blocks

The conceptual proposal for a so-called race-track three-dimensional data storage device based on domain walls in a dense array of vertical wires, revived the attention on cylindrical magnetic nanostructures. While mostly nanowires have been considered so far, nanotubes, i.e. a shell with an empty core, would open the door to core-shell structures, whose interfaces could […]

Creation of Magnetic Skyrmion Bubble Lattices by Ultrafast Laser in Ultrathin Films

Magnetic skyrmions are topologically nontrivial magnetic domains where the magnetization rotates in a fixed sense (chirality). They are usually created by magnetic fields or by non-homogeneous electric currents. Here S.G. Je et al. have shown that hexagonal skyrmion bubble lattices can be locally generated with ultrafast (30 fs) laser pulses. Their original optical approach to […]

Spin Hall and Spin Swapping Torques in Diffusive Ferromagnets

A complete set of the generalized drift-diffusion equations for a coupled charge and spin dynamics in ferromagnets in the presence of extrinsic spin-orbit coupling is derived from the quantum kinetic approach, covering major transport phenomena, such as the spin and anomalous Hall effects, spin swapping, spin precession, and relaxation processes. It is argued that the […]
