New magnetic flow has potential to revolutionise electronic devices

‘Altermagnetism’ discovery could deliver ‘thousand-fold increase’ in memory and speed of computing components
Magnetism swirls around a vortex in an altermagnetic material

An international research team has for the first time imaged and controlled a type of magnetic flow called altermagnetism, which physicists say could be used to develop faster and more reliable electronic devices.

A groundbreaking experiment at a powerful X-ray microscope in Sweden provides direct proof of the existence of altermagnetism, according to a paper published in Nature on Wednesday. Altermagnetic materials can sustain magnetic activity without themselves being magnetic.
