As if they were bubbles expanding in a just-opened bottle of champagne, tiny circular regions of magnetism can be rapidly enlarged to provide a precise method of measuring the magnetic properties of nanoparticles.
A new form of magnetic interaction which pushes a formerly two-dimensional phenomenon into the third dimension could open up a host of exciting new possibilities for data storage and advanced computing, scientists say.
A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Researchers from IMDEA Nanociencia and other European centres have discovered that the combination of graphene with cobalt offers relevant properties in the field of magnetism. This breakthrough sets the stage for the development ...
For many modern technical applications, such as superconducting wires for magnetic resonance imaging, engineers want as much as possible to get rid of electrical resistance and its accompanying production of heat.
In classical mechanics, particles are represented by point masses or rigid bodies, and in field theory by wave-like excitations or vibrations. Magnetic skyrmions are small, vortex-like spin textures of topological origin ...
Sometimes a good theory just needs to right materials to make it work. That's the case with recent findings by UT's physicists and their colleagues, who designed a two-dimensional magnetic system that points to the possibility ...
Researchers working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) coupled graphene, a monolayer form of carbon, with thin layers of magnetic materials like cobalt and nickel to produce ...
When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution.
Magnetic skyrmions offer the promise of next-generation memory and computing technologies, such as cache memory devices and cloud computing. Now A*STAR researchers have developed an innovative technique for making tunable ...
