Abstract

We found that the Field Induced Spin Density Wave (FISDW) phase in (DMET-TSeF)2I3 has an apparent high threshold field of about 25 T in spite of the very similar room temperature crystal structure and the Fermi surface compared to the salts studied so far with anions AuCl 2, AuBr2 and Aul2 which have threshold fields well below 10 T. The X-ray crystal structural studies down to 90 K do not show any special change in the structure. Possible reasons for the origin of the differences are discussed, and the sliding motion of the FISDW condensates at lower magnetic fields is proposed to be the most probable reason.
