Three-dimensional magnetic vortices have been discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf in Germany together with colleagues from the Paul Scherrer Institute in Switzerland ...

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 ...

Artificial intelligence is colliding with a hard physical limit: the energy and heat of conventional chips. As models scale ...

Researchers have observed three-dimensional magnetic vortex rings in a real-world magnetic material for the first time. Contrary to theoretical predictions, these rings – which are spin configurations ...

Stabilising curve: The arrows show the remnant magnetisation of a toroidal nanomagnet. On the outer edge (the right) we can see a vortex where the magnetisation spirals inwards to a point. An ...

ALBUQUERQUE, N.M. – Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. Researchers currently use all types of processes to try and create ...

(Nanowerk News) Researchers from NTNU are shedding light on magnetic materials at small scales by creating movies with the help of some extremely bright x-rays. The tiny square magnets, created by ...

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 ...
