Whereas high-temperature superconductivity in cuprates has been studied for 30 years, during the past year it has been reported in nickelates. This raises new questions for physicists and chemists about the mechanism of superconductivity — despite the electronic similarities of Cu and Ni, it seems that nickelate superconductivity requires consideration of a second orbital.

超导镍时代的曙光

铜酸盐中的高温超导性已经研究了30年，而在过去的一年中，镍酸盐中已经报道了这种超导性。这给物理学家和化学家们提出了有关超导机制的新问题-尽管铜和镍的电子相似，但似乎镍酸盐超导性需要考虑第二轨道。铜酸盐中的高温超导性已经研究了30年，而在过去的一年中，镍酸盐中已经报道了这种超导性。这给物理学家和化学家提出了有关超导机制的新问题。
