Sentences with phrase «magnetic vortices in»

In an earlier study, MIPT physicists excited magnetic vortices in spintronic devices based on a ferromagnetic material and a topological insulator.

«This suggests that Majorana zero modes are likely to exist, bound to magnetic vortices in this material, but we will have to do other types of measurements to find it.»

Together with colleagues from Forschungszentrum Jülich, the University of Edinburgh and the University of Nottingham, Almeida has studied the magnetic vortices in magnetite nanocrystals.

When placed in a magnetic field, many superconductors display swirling vortices of electric current — a hallmark of the standard superconductivity theory.

To the list of scary things in space you can now add giant magnetic vortices.

The team found that this «pins» the magnetic flux lines in place as the wires sweep through the field, preventing the formation of swirling magnetic vortices that reduce current flow.

A team of researchers at the Brazilian Center for Physics Research is studying the motion of vortex domain walls — local regions of charge that collectively store information via their configuration — driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y - like branch.

And the total sum of the winding numbers of vortices that wink in and out of existence as a magnetic field is applied around the doughnut always stays the same.

In the magnetic vortices — the skyrmions — the «atomic bar magnets» of the iron atoms spin around (orange and green arrows) and have an opposite orientation in their centres (blue arrowsIn the magnetic vortices — the skyrmions — the «atomic bar magnets» of the iron atoms spin around (orange and green arrows) and have an opposite orientation in their centres (blue arrowsin their centres (blue arrows).

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.

Magnetic vortices — so - called skyrmions — were predicted theoretically more than 25 years ago, but it has only been possible to observe them experimentally in magnetic materials in recenMagnetic vortices — so - called skyrmions — were predicted theoretically more than 25 years ago, but it has only been possible to observe them experimentally in magnetic materials in recenmagnetic materials in recent years.

In about one - third of the cases, she says, the magnetic vortices preceded a flare — sometimes up to 3 days before it erupted.

These defects «pin» in place, or trap, the microscopic magnetic vortices that form when the superconductor is placed in a strong magnetic field, such as those generated by magnets in magnetic resonance imaging (MRI) machines.

The experiments in Jülich showed that although the magnetic vortices alter in strength and direction when heated up, they go back to their original state as they cool down.

These bifurcations cause vortex - antivortex pairs to move together along the «magnetic roads» either in one orientation or the opposite, depending on their polarities.

It's as if the conducting paths for vortex motion in the magnetic trilayers can be dynamically rewired.

A group of researchers at CNRS, Forschungszentrum Juelich (FZJ), and Helmholtz Zentrum Dresden Rossendorf (HZDR) have developed nanoscale components that apart from storing information in magnetic vortices enable reading these out very efficiently.
