| Abstract: | Magnetoresistance measurements have been carried out along the highly conducting a axis in the fieldinduced spin-density wave (FISDW) phase of hydrogenated and deuterated (TMTSF)2ClO4 for various cooling rates through the anion ordering temperature. With increasing the cooling rate, (i) the high-field phase boundary βHI , observed at 27 T in hydrogenated samples for slowly cooled, is shifted towards a lower field, (ii) the last semimetallic SDW phase below βHI is suppressed, and (iii) the FISDW insulating phase above βHI is enhanced in both salts. The cooling rate dependence of the FISDW transition and of βHI in both salts can be explained by taking into account the peculiar SDW nesting vector stabilized by the dimerized gap due to anion ordering. |
