论文摘要
无论是在理论上还是实验室上，尼伯族都是研究最多的超导体之一。在超导应用的所有分支中，从强大的磁铁到量子计算都非常重要。因此，必须详细了解其基本属性。 Here we use the results of recent microscopic calculations of anisotropic electronic, phonon, and superconducting properties, and apply thermodynamic criterion for the type of superconductivity, more accurate and straightforward than a conventional Ginzburg-Landau parameter $κ$ - based delineation, to show that pure niobium is a type-I superconductor in the clean limit.然而，疾病（杂质，缺陷，应变，压力）将其变成II型超导体。
Niobium is one of the most researched superconductors, both theoretically and experimentally. It is enormously significant in all branches of superconducting applications, from powerful magnets to quantum computing. It is, therefore, imperative to understand its fundamental properties in great detail. Here we use the results of recent microscopic calculations of anisotropic electronic, phonon, and superconducting properties, and apply thermodynamic criterion for the type of superconductivity, more accurate and straightforward than a conventional Ginzburg-Landau parameter $κ$ - based delineation, to show that pure niobium is a type-I superconductor in the clean limit. However, disorder (impurities, defects, strain, stress) pushes it to become a type-II superconductor.
