Sentences with phrase «skyrmions with»

This implies that the present findings can be extended to all skyrmions with the same topology.

Not exact matches

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

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.

For skyrmion - based racetrack memories to compete with current technologies, skyrmions must be small and move quickly and easily through a material.

Once skyrmions behave as desired, creating a racetrack memory with them is an obvious next step.

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.

Materials scientists still need to find an antiferromagnetic material with the necessary properties to form skyrmions, Kläui says.

To make such a system work with skyrmions, scientists need to make the knots easier to wrangle at room temperature.

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.

«Our study provides the experimenters with recipes for making skyrmions à la carte,» explained Bertrand Dupé.
