4 New High-Temperature Superconductors
Physicists discovered a second family of high-temperature superconductors, materials that carry electricity without resistance at temperatures inexplicably far above absolute zero. The advance deepened the biggest mystery in condensed-matter physics.
In February, a group in Japan reported the first material, fluorine-doped lanthanum iron arsenic oxide (LaFeAsO(1-x)Fx), which is superconducting up to a "critical temperature" of 26 kelvin. Within 3 months, four groups in China had replaced the lanthanum with elements such as praseodymium and samarium and driven the temperature for resistance-free flow up to 55 kelvin. Others have since found compounds with different crystal structures and have bumped the critical temperature up to 56 kelvin.
For a critical temperature, that's not so hot. The record is 138 kelvin for members of the other family of high-temperature superconductors, the copper-and-oxygen, or "cuprate," compounds discovered in 1986. Still, the iron-based materials have created a stir, in part because they might help solve the enduring mystery of how the cuprates work. The $64,000 question is whether the two families work the same way. So far, evidence points in both directions. ---------------------------------------------------------- 科大的相关成果是陈仙辉教授的研究小组今年做出来的，发表在最顶级的期刊Nature上。 Within 3 months, four groups in China had replaced the lanthanum with elements such as praseodymium ~~~~~~~~~~~~ 物理所赵忠贤（科大校友）的工作 and samarium~~~~~~~~ 科大陈仙辉的工作 and driven the temperature for resistance-free flow up to 55 kelvin. ~~~~~~~~~~~~~~~~~~~ 物理所赵忠贤(科大校友)的工作 Others have since found compounds with different crystal structures and have bumped the critical temperature up to 56 kelvin. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 科大陈仙辉的工作 作者: 棍哥 时间: 2008-12-27 15:55
