    Abstract

    We present several new experimental results related to the occurrence and pressure dependence of the magnetic field induced spin density wave (FISDW) transitions and related high field phenomena in the Bechgaard salts. In the classic (TMTSF)2PF6 we show the pressure dependence of the frequencies for the FISDW transitions and the "fast" oscillations and the field for the N=0 state. We use thermopower and sound velocity to further study the phase diagram in (TMTSF)2ClO4. The thermopower points to a collective state from 7.5T to 27T and a new semiconducting phase above the reentrant transition. In studies of (TMTSF)2NO3 we find there is no FISDW state in contradiction to the "standard model" but in agreement with the theory of Yakovenko that relates superconductivity and the FISDW.
