X-ray analysis shows link between both kinds of superconductivity.(SUPERCONDUCTORS)
Advanced Ceramics Report, April, 2007
Researchers from Brigham Young University and the University of Tennessee, both USA, have taken a step closer to explaining the disparity between high- and low-temperature superconducting ceramics.
The researchers--Assistant Professor of Physics at Brigham Young, Branton Campbell, and Pengcheng Daiand, University of Tenessee--took tiny samples of ceramic crystals to Argonne National Laboratory for X-ray examination. There they shined a needle-thin X-ray beam on the crystals and mapped out the pattern of scattered X-rays to determine the location and type of each atom in the crystal structure. They also used a similar technique called neutron powder diffraction.
There are two principal types of copper-oxide ceramics that don't conduct electricity at...
