Abstract:
Using various transport and magnetotransport probes we study the
coexistence of spin-density wave and superconductor states in
(TMTSF)$_2$ClO$_4$ at various degrees of ClO$_4$ anions ordering. In the
two-phase complex state when both superconductivity and spin-density wave are
observed in transport, we find prehistory effects, enhancement of the
superconducting critical field, and strong spatial anisotropy of the
superconducting state. These features are inconsistent with the conventional
model of structural inhomogeneities produced by anion ordering transition.
We reveal instead that superconductor and spin-density wave regions overlap
on the temperature – dimerization gap $V$ phase diagram, where $V$ is varied
by anion ordering. The effect of anion ordering on (TMTSF)$_2$ClO$_4$
properties is thus analogous to that of pressure on (TMTSF)$_2$X (X$\,=\,$PF$_6$ or
AsF$_6$), thereby unifying general picture of the coexistence of
superconductivity and spin-density wave in these compounds.
