Abstract
ESR measurements were performed to investigate the
low-temperature electronic states of (TMTTF)
2MF
6 (
M = P, As, Sb and their mixed alloys). The temperature dependence of the ESR linewidth,
, of AsF
6 does not change its anisotropy at around
. On the other hand, PF
6 and some P-AsF
6 alloys show
changes of the
anisotropy at around
, suggesting
reconstruction of electronic charges. We propose the possible charge
ordering configuration in the vicinity of the low temperature ground states
from the ESR point of view.
Key words. TMTTF - Charge Ordering - ESR.
