We calculate the strong-coupling corrections to the Ginzburg-Landau free-energy functional in a strong magnetic field and analyze local and global minima of this functional. We show that in the case of a Fermi gas with repulsion the global minima in strong magnetic fields correspond only to the A1 and A2 phases discovered by Anderson, Brink-man, and Morel. © 7995 American Institute of Physics.
