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 ...
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, ...
Artistic illustration of Floquet-engineered magnons: Using time as a resource, a static magnetic vortex evolves into a periodically driven state whose gyration generates a magnon frequency comb.
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 ...
Pinning at local defects is a significant road block for the successful implementation of technological paradigms which rely on the dynamic properties of non-trivial magnetic textures. Here, a ...
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 ...
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 ...
The discovery of superconductivity more than a century ago has significantly changed our world. The story began in 1911 when the Dutch physicist Heike Kamerlingh Onnes observed that the electrical ...
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 ...
Analyzing magnetic nanostructures with a high resolution is a test-and-measurement challenge, but it’s important for both advanced physics insight as well as real-world products such as high-density ...
