Recently, observation of new topological magnetic structures represented by skyrmions is expected to provide new paths in constructing spintronic devices. In magnetic bubbles, although these are ...

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 ...

Vortex is ubiquitous in nature including spiral arms of galaxy, planet rotation, hurricane (tornado). A vortex is a typical and well-known magnetic domain structure in dimensionally confined ...

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 ...

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 ...

Magnets often harbour hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is 'sticky' on one side but not the other. The secret lies in the way the magnetisation is arranged in ...

For the first time, researchers have recorded a '3D film' of magnetic processes on the nanometer scale. This reveals a variety of dynamics inside the material, including the motion of swirling ...

In this analogy, a vortex at the center of a water tank replaces the solenoid that creates a magnetic field in the quantum ...
