Electroless plating to produce flux-closure nanotube for three-dimensional spintronics building blocks (December 18th, 2018)
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 […]
Read moreCreation of Magnetic Skyrmion Bubble Lattices by Ultrafast Laser in Ultrathin Films (December 18th, 2018)
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 […]

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 […]
Read moreSignificant Dzyaloshinskii–Moriya interaction at graphene/ferromagnet interfaces due to the Rashba effect (December 18th, 2018)
Despite being a weak spin–orbit coupling material, graphene demonstrated to induce significant Dzyaloshinskii–Moriya interaction due to the Rashba effect leading to formation of chiral spin textures in adjacent ferromagnet (FM) at graphene/FM interfaces. First-principles calculations and experiments using spin-polarized electron microscopy show that this graphene-induced Dzyaloshinskii–Moriya interaction can have a similar magnitude to that at […]
Read more[POSITION FILLED] Post-doctoral position in spintronics on magnetic skyrmions (December 18th, 2018)
Spintec invites application for a postdoctoral fellowship in spintronics on magnetic skyrmions. Magnetic skyrmions are nm scale topological spin texture that hold great promise for storing and manipulating the information at the nanoscale. Spintec recently demonstrated magnetic skyrmions at room temperature in ultrathin nanostructures [1] as well as their manipulation using electric field [2,3] and light [4] […]
Read more[POSITION FILLED] 30 months post-doc position – Magnetic and electric characterization of core-shell nanotubes for 3D spintronics (December 14th, 2018)
Spintronics has become a mature technology for applications, such as magnetic field sensing and solid-state memories. However, existing concepts are almost exclusively based on planar processes such as thin film deposition and patterning. Extending spintronics to 3D devices would provide new integrated functionalities such as three-dimensional magnetic field sensors, and also open prospects for an […]

C3DS stands for Chemistry for three-dimensional Spintronics, and is a 36-month ANR-DFG project (2019-2022). Spintronics has become a mature technology for applications, such as magnetic field sensing and solid-state memories. However, it is almost exclusively based on planar processes such as thin film deposition and patterning. Extending spintronics to 3D devices would provide new integrated […]
