Scientists achieve high temperature milestone in silicon spintronics

(PhysOrg.com) -- Researchers in the Materials Science and Technology division of the Naval Research Laboratory have recently demonstrated electrical injection, detection and precession of spin accumulation in silicon, the cornerstone material of modern device technology, at temperatures up to 225 degrees Celsius.

Free-floating electrons on top of liquid helium yield insights into their transport behavior

The multibillion dollar computer industry hinges on the ability to efficiently pass an electric current through a material. However, in any electronic device such as a computer transistor, the influence of the materials atom’s inevitably masks the interactions between the electrons. Using a custom-designed system, a research team from the RIKEN Advanced Science Institute, Wako, in collaboration with colleagues from the University of Konstanz, Germany, has completed the first study of the transport of single floating electrons free of external influences.

Researchers find magnetic link to high-temperature superconductivity

Researchers from the Stanford Institute for Materials and Energy Science, a joint SLAC-Stanford institute, have seen strong indications of a relationship between the superconductive and magnetic properties of high-temperature superconductors -- a relationship long suspected but difficult to investigate experimentally. Any step toward a real understanding of high temperature superconductors is a big step right now. Today's superconductors need extreme cold to keep conducting electricity with 100 percent efficiency, but extreme cold is not cheap
