Magnetic field influence on the spin-density wave of the organic conductor (TMTSF)2NO3

We present the influence of a transverse magnetic field on the spindensity wave (SDW) ground state of the organic conductor (TMTSF)2NO3. Magnetic field increases the single-particle activation energy. A finite magnetic field (HC induces discontinuities in the magnetoresistance behaviour and its value is temperature dependent. The threshold electric field (ET) for the SDW sliding increases in a magnetic field. All observed effects are strongly angle-dependent indicating that they are determined by the magnetic field component along the least-conduction (c*) direction. We discuss these results in the framework of a theoretical model for the SDW with large imperfect nesting.
