Abstract
We analyse thermodynamic properties of band electrons in the normal
state of relaxed (TMTSF)2ClO4 with transverse dimerization
potential V due to anion ordering and with a finite external
magnetic field. Providing the exact solution for electron spectrum,
we extend the scope of analysis from perturbative limit covered in
previous literature to the physically relevant regime of large
dimerizing potentials comparable to the electron interchain hopping
t. The one-electron spectrum shows characteristic oscillations,
periodic in inverse magnetic field, best fitted with
. The same oscillations are present in electron free energy and
specific heat. We find that the amplitude of thermodynamic
oscillations drastically increases by changing the magnitude of
dimerizing potential towards
, thus adding an important
contribution to the set of already known oscillatory mechanisms.
