Abstract / Description:Magnetoresistance and Hall resistance measurements have been
carried out in the FISDW phase of deuterated (TMTSF)(2)ClO4 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)(2)ClO4. A possible ground
state of the FISDW phase of (TMTSF)(2)ClO4 for various cooling
rates is discussed from the viewpoint of the peculiar SDW
nesting vector stabilized by the dimerized gap due to anion
ordering.
