Superconductivity in a nickel oxide material
Scientists at the US Department of Energy's
National Accelerator Laboratory and Stanford University have made the first
nickel oxide material that shows clear signs of superconductivity - the ability
to transmit electrical current with no loss.
Also known as a nickelate, it is the first in a potential new family of unconventional superconductors that is very similar to the copper oxides, or cuprates, and promises to revolutionize electronic devices, power transmission and other technologies. Perovskite - a material defined by its unique, double-pyramid atomic structure - that contained neodymium, nickel and oxygen was doped by adding strontium; this is a common process that adds chemicals to a material to make more of its electrons flow freely.
tests revealed that the nickelate was indeed superconducting in a temperature
range from 9-15 kelvins - incredibly cold, but a first start, with
possibilities of higher temperatures ahead.the discovery could help crack the
mystery of how high-temperature superconductors work.
