通过对L12超导体的研究,我们得出了这类超导体临界温度的表达式Tc=(15.9TBV(B)GA)/(M1/2V(L12)GB)。其中TB是B组元的超导转变温度,V(B)是B组元的原子体积,V(L12)为L12化合物的平均原子体积,M是L12化合物的平均原子量,GA,GB分别为A组元、B组元的Gordy电负性值。Through the examination of L12 type superconductors, we obtained the expression for the superconducting critical temperature Tc of L12 type superconductors: Tc=(15.9TBV(B)GA)/(M1/2 V(L12)GB) where TB is the superconducting critical temperature of pure B, V(B) is the atomie volume of pure B, V (L12) is the average atomic volume of the L12 type compound, M is the average atomic wight of the compound, and GA ,GB are Gordy electronegative values.
