ORNL examines clues for superconductivity in an iron-based material
Oak Ridge TN (SPX) May 07, 2014 - For the first time, scientists have a clearer understanding of how to control the appearance of a superconducting phase in a material, adding crucial fundamental knowledge and perhaps setting the stage for advances in the field of superconductivity. The paper, published in Physical Review Letters, focuses on a calcium-iron-arsenide single crystal, which has structural, thermodynamic and tr ... more
