Abstract

A recent theory of the magnetic-field-induced spin-density wave (FISDW) transitions observed in the Bechgaard Salts (TMTSF)2X emphasizes the role of the superconducting pairing interaction in FISDW formation. No superconductivity is observed in (TMTSF)2NO3, unlike other metallic Bechgaard salts. Our study of (TMTSF)2NO3 in pressure up to 13 kbar, temperature down to 0.5 K, and magnetic field up to 30 T shows no sign of FISDW. The ‘‘rapid’’ magnetoresistance oscillations observed but unexplained in other Bechgaard salts are also observed here.
