1986年，国际商业机器公司(IBM)苏黎世研究实验室工作的德国物理学家柏诺兹(J. Georg Bednorz)和瑞士物理学家缪勒(K. Alexander Müller)在自己制备的钡镧铜氧(Ba-La-Cu-O)样品中，利用电阻测量发现了35K超导电性的 ...
Titan shines light on high-temperature superconductor pathway
In conventional, low-temperature superconductivity (left), so-called Cooper pairing arises from the presence of an electron Fermi sea. In the pseudogap regime of the cuprate superconductors (right), parts of the Fermi sea are "dried out" …more.
Superconductivity Hypothesis Gets Some Experimental Confirmation
Transition temperatures tend to be close to 0 K or -273 C. At even slightly higher temperatures, the materials tend to lose their superconducting properties; indeed, at room temperature most superconductors are very poor conductors. Superconductors are ...
A proposed superconductivity theory receives exclusive experimental confirmation
In 1987, some high-temperature superconductors, called cuprates, were discovered by physicists Georg Bednorz and Alexander Müller, so named because they all contain copper and oxygen. These new materials have properties which have raised profound ...
