Researchers Convert Magnetic Order into Electrical Signals
A new nanodevice successfully transforms hidden magnetic states in altermagnets into readable electrical signals.
Updated on Oct. 28, 2026 in Materials Science
Scientists have developed a nanodevice that converts hidden magnetic order in altermagnets into a measurable electrical signal. This breakthrough demonstrates a novel method for reading magnetic information.
Why it matters
This development offers a potential path for future memory technologies, overcoming challenges associated with reading magnetic states. It enables a more efficient way to process information at the nanoscale.
The nanodevice operates across a distance of 300 nanometres, which is approximately one-hundredth the thickness of a human hair. Researchers utilized a metal conduit to propagate spin currents from the altermagnet to the detector.
The players
CIC nanoGUNE
CIC nanoGUNE is a research institution dedicated to nanoscience and nanotechnology located in Spain.
The details
An electric current is passed through the altermagnet to generate a spin current, which then travels through a metal conduit. This process allows the system to produce a detectable electrical signal from the material's magnetic order.
Timeline
The research was officially published in the journal Nature on October 28, 2026.
