Sentences with phrase «on skyrmion»

In a 2008 paper in Science, Parkin and colleagues demonstrated the beginnings of a racetrack memory based not on skyrmions, but on magnetic features called domain walls, which separate regions with different directions of magnetization in a material.

A microwave nano - oscillator based on skyrmions could operate at three resonant frequencies, corresponding to the three modes.

Not exact matches

Today, the idea — with and without skyrmions — has caught on.

On traditional hard drives, the magnetic regions that store data are about 10 times as large as the smallest skyrmions.

On the racetrack, skyrmions might hit a wall instead of staying in their lanes.

Now, researchers are seeking new kinds of skyrmions that stay on track.

But physicists are now fashioning a new parallel system called spintronics — of which skyrmions are a part — based on the motion of electron spin, that property that makes atoms magnetic (SN Online: 9/26/17).

Physicists are now on the hunt for skyrmions within a different realm: antiferromagnetic materials.

In racetrack devices, information - holding skyrmions would speed along a magnetic nanoribbon, like cars on the Indianapolis Motor Speedway.

The researchers focused on a type of skyrmion called the Néel skyrmion, which exists in ultrathin films deposited on metals with a strong DMI.

When the scientists switched on a specially designed magnetic field, the spins arranged into a twisting structure of loops, knotting up into a configuration known as a Shankar skyrmion.

Hall and colleagues created their skyrmion in a state of matter called a Bose - Einstein condensate, composed of atoms cooled to a temperature so low that they all take on the same quantum state and begin acting as if they are one unified entity (SN: 10/13/01, p. 230).

«The measurements show that the skyrmions move on a very complex trajectory, a so - called hypo - cycloid,» says Krüger.

In order to use skyrmions as a storage medium, it must be possible to manufacture the surfaces or interfaces on a sufficiently large scale, they must contain enough of the magnetic material, and the magnetic vortex must also occur at room temperature.

However, there is still a long way to go until the first memory applications based on magnetic skyrmions are produced.

Skyrmions, for example, are a kind of nanomagnet, composed of a spin - correlated ensemble of electrons acting as a topological magnet on certain microscopic surfaces.

«Our new method is the simplest way to generate skyrmion bubbles thus far,» said Argonne postdoctoral researcher Wanjun Jiang, the first author on the study.
