New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material. Developed by physicists at Martin Luther University Halle-Wittenberg (MLU), the method could advance the production of smaller, faster and more energy-efficient components for data storage and information processing. The physicists have published their results in the journal Applied Physics Letters.

Scientists have made a pivotal breakthrough in the important, emerging field of spintronics—which could lead to a new high speed energy efficient data technology.

An international team of researchers, including the University of Exeter, has made a revolutionary discovery that has the potential to provide high speed, low power-usage for some of the world’s most well-used electronic devices.

While today’s information technology relies on electronics that consumes a huge amount of energy, the electrons within electric currents can also transfer a form of angular momentum called spin.

‘Spin-based electronics or ‘spintronics’, that exploits spin current, has the potential to be not just significantly faster, but also more energy efficient.

Researchers have developed a revolutionary way to encode computational information without using electrical current. As a global first, this could lead to faster technological devices that could efficiently use energy without overheating.

Modern computer memory encodes information by switching magnetic bits within devices. Now, a ground-breaking study conducted by researchers from the Department of Electrical and Computer Engineering at the National University of Singapore has found a new efficient way of using ‘spin waves’ to switch magnetisation at room temperature for more energy-efficient spin memory and logic devices.

Electric currents drive all our electronic devices. The emerging field of spintronics looks to replace electric currents with what are known as spin currents. Researchers from the University of Tokyo have made a breakthrough in this area. Their discovery of the magnetic spin Hall effect could lead to low-power, high-speed and high-capacity devices. They have created sample devices which can further research into potential applications.

“Electricity lit up the world and electronics connected it,” says Professor Yoshichika Otani from the Institute for Solid State Physics. “Spintronics will be the next step forward in this procession and we can only imagine what advances it may bring.”
