Artificial Spin Ice: A New Playground to Better Understand Magnetism

Apr. 27, 2015 — For the first time, nanomagnet islands or arrays were arranged into an exotic structure (called “shakti”) that does not directly relate to any known natural material. The “shakti” artificial ... read more

Apr. 22, 2015 — Researchers have discovered that electron spin brings a previously unknown degree of order to the high entropy alloy nickel iron chromium cobalt -- and may play a role in giving the alloy its ... read more

Quantum Hall Effect: Quantization of 'Surface Dirac States' Could Lead to Exotic Applications

Apr. 14, 2015 — Researchers have uncovered the first evidence of an unusual quantum phenomenon -- the integer quantum Hall effect -- in a new type of film, called a 3-D topological insulator. This discovery could ... read more

Apr. 13, 2015 — Researchers have discovered a new way of manipulating the magnetic domain walls in ultrathin magnets that could one day revolutionize the electronics industry through a technology called ... read more

Apr. 13, 2015 — Physicists have narrowed the theoretical limits for where the 'speed limit' lies for quantum computers. The findings, which offer a better description of how quickly information can travel ... read more

Apr. 10, 2015 — Scientists have encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to ... read more

Apr. 10, 2015 — Chemists have reviewed the potential for graphene-organic composite materials in electronics. The researchers show how organic semiconductors can be used to better process graphene, and to tune its ... read more

Apr. 10, 2015 — Researchers have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has ... read more

Mar. 25, 2015 — Scientists have presented the first spin-controlled oxygen adsorption experiment indicating that the rate of surface oxidation is strongly affected by the electron spin of ... read more

'Goldilocks Material' Could Change Spintronics

Mar. 24, 2015 — Attempting to develop a novel type of permanent magnet, a team of researchers has discovered a new class of magnetic materials based on Mn-Ga alloys. Described as a zero-moment half metal, the new ... read more

Quantum Computing: One Step Closer With Defect-Free Logic Gate

Mar. 19, 2015 — What does hair styling have in common with quantum computing? The braiding pattern has inspired scientists as a potential new approach to quantum calculation. But due to their tight assembly, such ... read more

Scientists Move Closer to 'Two for One Deal' on Solar Cell Efficiency

Mar. 16, 2015 — The underlying mechanism behind an enigmatic process called 'singlet exciton fission,' which could enable the development of significantly more powerful solar cells, has been identified by ... read more

New Remote Control for Molecular Motors

Mar. 16, 2015 — Magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate may intuitively be difficult to achieve. However, physicists have just demonstrated ... read more

Mar. 11, 2015 — Graphene is a form of carbon in which the atoms are connected in a honeycomb structure. The possible ‘holy grail’ has this same structure, but is made of nanocrystals of mercury and tellurium. In ... read more

Mar. 9, 2015 — At the origin of the properties of high-temperature superconductors lies a phenomenon that is too fast to be observed experimentally with conventional methods. Scientists have applied a sophisticated ... read more

Mar. 3, 2015 — Scientists have found a new way to electrically read out the orientation of magnetic vortices in nanodisks. Their new method relies on measuring characteristic microwaves emanating from the vortices. ... read more

Feb. 25, 2015 — Magnetic nanoparticles can increase the performance of solar cells made from polymers -- provided the mix is right. Adding about one per cent of such nanoparticles by weight makes the solar cells ... read more

Feb. 25, 2015 — Engineers have developed a new concept for accelerating data transfer in server farms. To this end, the team has applied a quantum-mechanical variable, i.e. the spin. Researchers are optimizing the ... read more

Feb. 23, 2015 — Scientists have provided the first direct experimental insight into the secret quantum life of dichromium. Whereas in its normal state the 12 valence electrons form a strong multiple bond between the ... read more

Feb. 17, 2015 — Research teams from Paris, Madrid and Berlin have observed for the first time how magnetic domains mutually influence one another at interfaces of spintronic components. Using measurements taken at ... read more
