FERMION ANALOGY FOR LAYERED SUPERCONDUCTING FILMS IN PARALLEL MAGNETIC-FIELD

The equivalence between the Lawrence-Doniaeh model for films of extrem e type-II layered superconductors and a generalization of the back-sca ttering model for spin-(1/2) electrons in one dimension is demonstrate d. This fermion analogy is then exploited to obtain an anomalous H-par allel to(-1) tail for the parallel equilibrium magnetization of the mi nimal double-layer case in the limit of high parallel magnetic fields H-parallel to for temperatures in the critical regime.
