摘要：

The field-induced spin-density-wave state in (TMTSF)2ClO4, where TMTSF is tetramethyltetraselenafulvalene, develops because the field diminishes the antinesting terms, tb, to restore the spin-density wave (SDW) that would exist at tb=0 despite the anion gap in ClO4. The gap changes the wave functions symmetry for nested subbandsone of them changes sign upon crossing the new zone boundary, destroying the coherence of paired electrons at H 0. Competition between the two phenomena leads to a reentrance of the metallic state. Magnetic breakdown is unable to restore a PF6-type ground state and reveals itself in a pattern of peaks for TSDW(H) periodic in H-1. © 1995 The American Physical Society.
