Sentences with phrase «of skyrmions»

Felser, Parkin and colleagues detected a new kind of skyrmion, an antiskyrmion, in a thin layer of such a material.

The first type of skyrmion detected, called a Bloch skyrmion, appears in asymmetric crystals.

For sufficiently large currents, this setup will allow the creation of a skyrmion of 10 - 20 nanometers in size, underneath the nanocontact.

When condensed matter physicist Christos Panagopoulos of Nanyang Technological University in Singapore and colleagues fiddled with the composition of layers of iridium, iron, cobalt and platinum, a variety of skyrmions swirled into existence.

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

In contrast with hard drive disks, which are spun to enable data to be entered or read, in the case of skyrmion - based devices the bits could simply be moved right through the material, similar to how electricity flows through a wire.

Now, a research group in Singapore has used computer simulations to further probe the behaviors of skyrmions, gaining insight that can help scientists and engineers better study the quasi-particles in experiments.

Although researchers have studied how groups of skyrmions behave, little is known about their internal behaviors, Kuok said.

A few months ago, several publications reported the successful experimental observation of skyrmions,» said Dr. Gustav Bihlmayer from the Forschungszentrum Jülich.

The inertia of the skyrmion stems from the fact that the whirl can deform.

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.

«This effect has to be taken into account to enable the distinct positioning of the skyrmion in the memory.»

«The synchronized dance of skyrmion spins.»

«Physicists observe motion of skyrmions.»

«This might be an interesting compromise to seek, especially in the context of skyrmion - based data storage,» added Manchon.

Aurelien Manchon, an Associate Professor of Material Science and Engineering at the University, notes that one of the main reasons for the appeal of skyrmions is their ability to avoid defects or uneven patches in thin films that would normally trap or «pin» a magnetic charge.

So far, Schäffer says there are only a few realized applications of these skyrmions, which are relatively new to the forefront of solid state physics, but their properties and the current research capabilities make them ripe for next generation technologies.

«The nice interplay between the mathematical concept of topological energy barriers and the physical transport properties of skyrmions, which are highly mobile, are the outstanding aspects for me.»

After an initial discovery in Germany, this is a field that has been widely studied in France, including by the Fert team, who recently demonstrated the possibility of occurrence of these skyrmions at room temperature, making even more likely their use in practice [2].

Scientists want to find a way to create 1 and 0 by using physics phenomena that don't actually change the atomic structure of the material — for example, making a line of skyrmions that could be read as 1s (skyrmion) and 0s (no skyrmion).

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

Just as there's more than one way to tie a knot, there are several different types of skyrmions, formed with various shapes of magnetic twists.

«The type of skyrmions you get is related to the crystal structure of the materials,» says physical chemist Claudia Felser of the Max Planck Institute for Chemical Physics of Solids in Dresden, Germany.

A chain of skyrmions could encode bits within a computer, with the presence of a skyrmion representing 1 and the absence representing 0.

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

Antiskyrmions also might be able to shrink down smaller than other kinds of skyrmions.
