Copyright(c)2005 The Physical Society of JapanThe effect of spatial modulation of the single-site anisotropy D on the ground state of the phase diagram contains the Haldane phase, large-D phase, N´eel phase of udud-type and u0d0-type. It is shown that the hidden antiferromagnetic order in the Haldane phase compatible with the spatial modulation of D-term get frozen resulting in the emergence of various types of N´eel orders. The investigation of the model with longer period D-modulation also confirms this picture.
