AN EXPRESSION FOR THE CRITICAL TEMPERATURE Tc OF L12 TYPE SUPERCONDUCTORS
Ll2超导体的Tc表达式

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.
