Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to researchers because they could be harnessed for new forms of data ...

Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as ...

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, ...

Magnetic vortices arise in nanoscale ferromagnetic elements when spins curl in-plane around a small, perpendicularly magnetised core. The resulting topological structure exhibits a gyrotropic mode in ...

On-demand control of stable toroidal vortices lays groundwork for robust wireless data encoding. (Nanowerk News) Researchers have created an optical device that can generate both electric and magnetic ...

Researchers have uncovered a new way to generate exotic oscillation states in tiny magnetic structures—using only minimal energy. By exciting magnetic waves, they triggered a delicate motion that ...

The electron spins in a magnetic vortex all point in parallel, either clockwise or counterclockwise. Spins in the crowded core of the vortex must point out of the plane, either up or down. The four ...

Magnetometry exploiting color center defects in diamond probes and magneto-optic imaging have been found to complement each other. This supports progress towards the creation of more effective data ...

Controlling this state paves the way for the creation of more intelligent, reconfigurable and energy-efficient devices that mimic the brain. The use of Big Data has multiplied the energy demand in ...

A magnetic vortex, known as a skyrmion (grey dot), being displaced into the corners of a triangular field by electrical currents, where it bounces off the sides. The potentials shown in red are ...
