Abstract
We report a study of the transverse-magnetoresistance anisotropy in th e spin-density wave phase of the organic conductor (TMTSF)2NO3 at temp eratures down to 1.8 K and in fields up to 6 tesla. The transverse mag netoresistance is highly anisotropic and obeys a temperature- and angu lar-dependent power law behaviour: DELTArho/rho congruent-to H(n) (1 l ess-than-or-equal-to n < 2). The indication of a possible field-induce d SDW phase is discussed. We suggest that the SDW with large imperfect nesting together with a periodic anion potential might be responsible for the observed magnetic-field effects.
