Sentences with phrase «which skyrmions»

Bloch skyrmions are found in the thick, asymmetric crystals in which skyrmions were first detected, and Néel skyrmions tend to show up in thin films.

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).

Not exact matches

Although skyrmions are made up of atoms, which remain stationary within the material, skyrmions can move around like a true particle, by sliding from one group of atoms to another.

Another idea is to use skyrmions for biologically inspired computers, which attempt to mimic the human brain (SN: 9/6/14, p. 10).

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.

Skyrmions, which dwell within such magnetic habitats, are composed of groups of atoms with their magnetic poles oriented in whorls.

At the same time, researchers are chasing after new kinds of skyrmions, which may be an even better fit for data storage.

The future of data storage is likely to be found in nanometer scale, stable magnetic whirls called skyrmions, which behave like particles in magnetic thin films.

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

The team showed that a magnetic skyrmion can be created under a nanocontact, in which a spin - polarized current is injected into the magnetic thin film providing a so - called spin torque to its magnetic moments.

Because the mode frequencies of skyrmions are in the microwave range, the quasi-particles could be used for new microwave nano - oscillators, which are important building blocks for microwave integrated circuits.

Once created, they can be transported over distances of several hundreds nanometers, which means that skyrmions can be created and manipulated in materials that have never before been considered for skyrmionics.

Schematically, skyrmions are pseudo-nanoparticles (see figure), which are expected to be very important for storing and processing information in computers.
