Abstract
We have observed a very large sensitivity to low magnetic field (i.e. below 0.5 Tesla) of the
low-temperature specific heat
Cp of the quasi-1D compound (TMTSF)
2PF
6 in
its spin-density wave (SDW) ground state.
This effect is independent on the field direction compared to that
of the crystal orientation (with H || either to
or
axis), and hence does not seem to be related in a direct way to the electronic SDW itself.
In addition, we did not
detect any feature in
Cp at the spin-flop transition (at
H=0.45 T, ||
axis).
