# Magnetic Fluctuations in a Charge-Ordered State of the One-Dimensional Extended Hubbard Model with a Half-Filled Band

@article{Yoshioka2002MagneticFI, title={Magnetic Fluctuations in a Charge-Ordered State of the One-Dimensional Extended Hubbard Model with a Half-Filled Band}, author={Hideo Yoshioka}, journal={Journal of the Physical Society of Japan}, year={2002}, volume={71}, pages={1812-1815} }

Magnetic properties in a charge-ordered state are examined for the extended Hubbard model at half-filling. Magnetic excitations, magnetic susceptibilities and a nuclear spin relaxation rate are calculated with taking account of fluctuations around the mean-field solution. The relevance of the present results to the observation in the 1:1 organic conductors, (TTM-TTP)I 3 , is discussed.

The ground-state phase diagram of the one-dimensional half-filled Hubbard model with on-site and nearest-neighbor repulsive interactions is reexamine and it is found that the umklapp scattering of parallel-spin electrons destabilizes the BCDW state and gives rise to a bicritical point where the CDW-BCDW and SDW- BCDW continuous-transition lines merge into theCDW-SDW first-order transition line.
