Stripe phase orders of charge and spin for the 2-D systems of strongly correlated electrons at and near half-filling

Abstract

Based on our earlier linearized Hubbard model approach, eve present the variation of charge and spin orders with doping rate for both the 50 x 2 lattice and the 14 x 14 square lattice of antiferromagnetically correlated electrons. It is shown that the charge stripe order as chain domain walls appears at a higher doping rate than the spin order, in agreement with observation. (C) 1999 Elsevier Science B.V. All rights reserved.
