Research at Lund University in Sweden has found a new way to create nano-sized magnetic particles using ultrafast laser light pulses. The discovery could pave the way for new and more energy-efficient technical components and become useful in the quantum computers of the future.

Magnetic skyrmions are sometimes described as magnetic vortices. Unlike ferromagnetic states — which occur in conventional magnets such as compasses and refrigerator magnets — the skyrmion state is quite peculiar: the orientation of the magnetization does not point in the same direction everywhere in the material, but is instead best described as a kind of swirling magnetism.

Skyrmions are of great interest to both basic researchand industry, as they can be used to manufactu...

Researchers have achieved, for the first time, electronically adjustable interactions between microwaves and a phenomenon in certain magnetic materials called spin waves. This could have application in quantum and classical information processing.

Working with theorists in the University of Chicago’s Pritzker School of Molecular Engineering, researchers in the U.S...

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.

Traditional electronic chips s...
