A team led by researchers from the National University of Singapore (NUS) has achieved a major breakthrough in magnetic interaction. By adding a special insulator, they make electrons "twirl" their neighbouring "dance partners" to transfer magnetic information over a longer range between two thin layers of magnetic materials. This novel technique enables magnetic information to make their way from one magnetic layer to another, synonymous to the encoding and transmission of data.
"The big data revolution relies on vast amount of digital information which are magnetically stored on hard disks in server farms across the planet. A bottleneck that stifles the progress of this emerging field lies in the demand for faster data transmission rates. The recent discovery by our team paves the way for the development of devices that operate in the terahertz frequency range, which makes encoding and transmission of data many times faster," explained Assistant Professor Ariando, who is from the NUS Nanoscience and Nanotechnology Institute (NUSNNI), and co-leader of the research team.
The findings were reported in the online edition of the journal Nature Communications on 16 March 2016.
