【表紙の説明】 超伝導臨界温度Tcの推移と各種超伝導体で最も高いTcを示す結晶構造:高圧下で合成された“超”水素化合物と単純金属(●)、銅酸化物(▲)、鉄系(■)の超伝導体。●は従来型、▲と■は非従来型超伝導体である。破線は窒素と液体天然ガスの沸点、南極最低気温の最低温度を示す。水素化合物のTcは地球表面の最低温度を超えた。 Temporal evolution of the superconducting critical temperature, Tc, and the crystal structures exhibiting highest-Tc in each families of superconductors: super-hydride synthesized under high-pressure and simple metals (●), cuprates (▲), iron-based (■). Solid circles indicate conventional superconductors, whereas solid triangles and squares are unconventional superconductors. Boiling temperature of nitrogen and liquid-natural-gas, LNG, and the record of the lowest air temperature in Antarctica are shown with the dashed-lines for reference. Tc of the hydrides exceeded the minimum temperature of the Earth's surface. |
