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.

TLDR
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.

TLDR
The extended Hubbard model in one dimension is studied for half-filled bands using a continuum theory based on the Luttinger model, and a possible equivalence to some recent studies of coupled two-dimensional XY models is discussed. Expand
