What's Happening?
Researchers have developed a technique called spin-torque driven skyrmion resonance (STSkR) to manipulate magnetic skyrmions, which are promising for ultra-dense, low-energy magnetic memory devices. Skyrmions are vortex-like spin structures with topological stability, making them resistant to deformations. The STSkR technique excites skyrmion precession using spin-polarized electric currents, allowing for precise quantification of spin-torque generation. This advancement addresses challenges in transporting and manipulating skyrmions, paving the way for their integration into future memory and logic devices.
