使用金-朗道理论在非常一般的条款，我们开发了一个简单的缩放程序，它允许建立温度依赖性的上临界场Hc 2和超导临界温度Tc的值的II型超导体从测量的可逆等温磁化。现有的实验数据的分析表明，归一化的依赖关系Hc 2的T/Tc几乎是相同的所有家庭的高Tc超导体在所有温度下的磁化数据是可用的。
Using the Ginzburg-Landau theory in very general terms, we develop a simple scaling procedure which allows to establish the temperature dependence of the upper critical field H c 2 and the value of the superconducting critical temperature T c of type-II superconductors from measurements of the reversible isothermal magnetization. An analysis of existing experimental data shows that the normalized dependencies of H c 2 on T/T c are practically identical for all families of high-T c superconductors at all temperatures for which the magnetization data are available.
