Researchers have unveiled a remarkably efficient bit-switch employing skyrmions.

Researchers from the Agency for Science, Technology, and Research (A*STAR) and the National University of Singapore (NUS) have introduced an extraordinary microelectronic device capable of functioning as a sustainable and high-performance “bit-switch”.

These innovative devices harness magnetic skyrmions, enabling them to operate using 1,000 times less power than conventional memory technologies. But what exactly are magnetic skyrmions?

Picture a small ball composed of magnetized material, where instead of the north and south poles aligning in a straight manner like a typical magnet, they spiral around the surface of the ball in twisted circles. This description captures the essence of magnetic skyrmions.
