In a recent letter [1],
the magnetic-field dependence of the
metal-insulator (MI)
transition temperature in the compound
was presented and was found in
agreement (Fig. 1)
with the theoretical prediction for the Peierls transition temperature,
, obtained by
Dieterich and Fulde [2]:
where
is the digamma-function. For low fields
, this gives a B2-dependence [2,3]:
The authors used this agreement to simultaneously validate two different assertions:
equation (1) describes well the magnetic-field dependence of the Peierls transition
temperature and the transition occurring in this compound is driven only by the electron-phonon
interaction (Peierls transition). In this comment, we would like to show that
equation (1) is not completely satisfactory and that the MI transition mechanism involved in
this compound is more complicated than claimed by the authors.
