Sentences with phrase «of magnetic domains»

Long stripes of magnetic domains appear in the magnetic material on one side of a tiny channel.

One possibility: time is just another spatial dimension except at the beginning of space and time This is perhaps like formation of an ice crystal or alignment of magnetic domains, a phase change in which time becomes timelike.

In the course of their research into the use of magnetic domain walls (local regions of magnetic «charge» usually driven by magnetic fields) to increase our capacity for information storage and logical processing, physicists at the University of Nottingham have discovered a phenomenon which has allowed them to «manipulate» the structure of a magnetic domain wall.

Not exact matches

To speed up these processes, researchers have recently started to explore the use of ultrashort laser pulses that can switch magnetic domains in solid - state materials.

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.

«Even if this particular material will probably not be used because of the low temperatures and strong magnetic domains required, our experiments show what this kind of control could, in principle, look like,» adds Simon Gerber, first author of the publication.

Previously it has been shown that the chirality can be manipulated by applying magnetic fields to complicated nanowire geometries, but the use of magnetic fields is wasteful of energy and limits the ability to address individual domain walls selectively.

IBM calls dubs it «racetrack memory,» because it uses magnetic domains to store information in columns of magnetic material (nanoscale «racetracks») arranged on the surface of a silicon wafer.

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.

The control and manipulation of these domain walls is crucial for successful realizing magnetic memory, logic and sensors devices.

«If you can image the size of the material's magnetic domains and how they evolve on small length scales, that gives you information about the value and strength of these interactions,» she added.

This involved applying a pulsed magnetic field that was perpendicular to the plane of the domain walls.

Therefore, the enhancement of the magnetic anisotropy of Fe3O4 nanoparticles in order to produce blocked magnetic single domain nanoparticles at room temperature is highly challenging.

Using nuclear magnetic resonance (NMR) spectroscopy, however, he found at least two different arrangements of the two domains in the protein: one open, one closed, neither resembling that of the crystal structure.
