Scientists at SLAC and Stanford show how high-temperature superconductivity emerges out of magnetism in an iron pnictide, a class of materials with great potential for making devices that conduct electricity with 100 percent efficiency.
A new study, based on an experiment at SLAC's X-ray laser, pins down a major factor behind the appearance of superconductivity—the ability to conduct electricity with 100 percent efficiency—in a promising copper-oxide material.
A new theory and computer simulation by SLAC and Stanford researchers rule out high-energy magnetic interactions as a major factor in making copper oxide materials perfect electrical conductors – superconductors – at relatively high temperatures.
Scientists have discovered a potential way to make graphene – a single layer of carbon atoms with great promise for future electronics – superconducting, a state in which it would carry electricity with 100 percent efficiency.
A team led by SLAC and Stanford scientists has made an important discovery toward understanding how a large group of complex copper oxide materials lose their electrical resistance at remarkably high temperatures.
Condensed-matter physicists the world over are in hot pursuit of a comprehensive understanding of high-temperature superconductivity, not just for its technological benefits but for the clues it holds to strongly correlated electron systems.
