ON THE HIGH-FIELD LIMITING PHASE IN (TMTSF)2CLO4

It is argued that the reentrant phenomenon from the field-induced spin density wave state to the normal state at H is-approximately-equal-to 25 T and the unidentified new high-field phase found in (TMTSF)2ClO4 can both be understood consistently within the framework of the so-called standard model and theory. We present detailed discussions in support of this argument by examining various experimental data and evaluating the phase diagram. A missing transition line in still higher fields is predicted.
