Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as 'magnons' in analogy to the electron, could ...

The center of a magnetic vortex emits spin waves with very short wavelengths in the presence of high-frequency alternating magnetic fields. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf have ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

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 ...

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 ...

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 ...
