Abstract

Magnetoresistance and Hall resistance measurements have been carried out in the FISDW phase of deuterated (TMTSF)2ClO4 for various cooling rates through the anion ordering temperature. The Hall resistance in the intermediate cooled state, observed a very stable quantum Hall state above 9.0 T for slowly cooled, shows a step-like change from the phase between 10 and 17 T to the phase between 20 and 25 T with hysteresis between 14 and 21 T. This result suggests that there is a new phase transition around 15 T in deuterated (TMTSF)2ClO4. A possible ground state of the FISDW phase of (TMTSF)2ClO4 for various cooling rates is discussed from the viewpoint of the peculiar SDW nesting vector stabilized by the dimerized gap due to anion ordering.
