Thouless' theory on the critical behavior of type II superconductors is extended for all temperatures. It is shown that, except for the dirty superconductors, where the scaling field ..delta..H/sub s/ = (..delta..H/sub s/)/sub GL/, the scaling field requires an additional temperature dependent coefficient lambda (i.e., ..delta..H/sub s/ = lambda (..delta..H/sub s/)/sub GL/). Here (..delta..H/sub s/)/sub GL/ is the generalized version of the Ginzburg-Landau expression introduced by Thouless. The parameter lambda is calculated for clean type II superconductors and for high-field type II superconductors with strong Pauli paramagnetism.
