Scientists have confirmed a third type of magnetism, known as altermagnetism, in a breakthrough that could lead to faster computers and more energy-efficient electronic devices.

The discovery was made by researchers at the US Department of Energy's SLAC National Accelerator Laboratory, providing experimental evidence of a magnetic state first proposed in 2022.

Studying manganese telluride, the team used advanced X-ray techniques to identify distinctive magnetic properties that distinguish altermagnets from conventional ferromagnets and antiferromagnets.

Unlike traditional magnetic materials, altermagnets combine opposing electron spins with the ability to generate spin-polarised currents, making them promising for next-generation memory and computing technologies.

The findings, published in Science, could advance spintronics, a field focused on developing faster and more energy-efficient electronic systems.
