Abstract
We investigate Knight shift in the charge ordered state
of the one-dimensional electron system nearly half-filling. It is shown that
the splitting of Knight shift occurs below the critical temperature of
charge ordering. This finding is different from the case of just
half-filling, where the splitting does not occur even in the charge ordered
state. In addition, we find the simple relations among the difference
between the shift in the charge rich site and that in the poor site and the
mount of the charge transfer.
Key words. Charge order - Knight shift - extended Hubbard model.
