Magnesium Diboride镁硼化物
In March 2001, Jun Akimitsu and colleagues at Aoyama-Gakuin University in Tokyo, Japan reported a superconducting transition temperature of 39 Kelvin for magnesium diboride. This has generated a great deal of excitement not only because this is the highest transition temperature yet observed for a type-II superconductor, but also because the materials used are quite common. 2001年3月，东京日本的东京大学的Jun Akimitsu及其同事报告了镁二硼化物的超导转变温度为39开尔文。这一发现不仅因为这是迄今为止观察到的II型超导体中最高的转变温度而引起广泛关注，还因为所用材料相当常见。
There will be a great deal of interest in whether the material can be used to form wires. If its mechanical properties can be managed, it could contribute significantly to making superconducting magnets. Sergey L. Bud'ko and colleagues at Iowa State University have formed wires from the material. They observed the isotope effect in this superconductor, suggesting that it follows the behavior of other conventional superconductors. The isotope effect is a signature of interaction with the crystal lattice via phonons, and is an indication that the superconductor may act according to the BCS theory of superconductivity. 对这种材料能否用来制造导线将会有很大兴趣。如果能控制其机械性能，它可能对制造超导磁体做出显著贡献。爱荷华州立大学的Sergey L. Bud'ko及其同事已用该材料制成了导线。他们观察到了这种超导体的同位素效应，这表明它可能与其他常规超导体具有相似的行为。同位素效应是声子与晶体格点相互作用的特征，表明这种超导体可能遵循BCS超导理论。

Superconducting Plutonium超导 plutonium
The plutonium compound PuCoGa5 has been found to be superconducting with a critical temperature of about 18 K. Gregory Stewart of the University of Florida and John Sarrao and colleagues at the Los Alamos National Laboratory reported this unexpected superconductor in the journal Nature. 钚化合物PuCoGa₅被发现具有超导性，其临界温度约为18 K。佛罗里达大学的Gregory Stewart和洛斯阿拉莫斯国家实验室的John Sarrao及其同事在《自然》杂志上报告了这种意外发现的超导体。
