The equivalence between the Lawrence-Doniach model for films of
extreme type-II layered superconductors and a generalization of
the back-scattering model for spin-(1/2) electrons in one dimension
is demonstrated. This fermion analogy is then exploited to obtain
an anomalous 
tail
for the parallel equilibrium magnetization of the minimal
double-layer case in the limit of high
parallel magnetic fields 
for temperatures
in the critical regime.
