Аннотация:We examine the procedure for the thermodynamical derivation of the Ginzburg-Landau equation for current, which is given unclear and contradictory interpretations in existing textbooks. We clarify all the steps of this procedure and find, as a consequence, a limitation on the validity range of the thermodynamic Ginzburg-Landau theory that has not previously been explicitly stated. We conclude that the thermodynamic theory is applicable only to a superconducting specimen that is not part of an external current-carrying loop.
