• Phase diagram of S :: 1 XXZ chain in a staggered naagnetic field is obtained ntrnaerically. TlaeBerezinskii-Kosterlitz-Thou[ess transition betxveen the XY and the antiferroznagnetic phatses isstudied by the level-spectroscop3'. lVIoreox'er xve find tlaat tJaere is no distinction betxveen tlaeHaldane and the anti['erroun?rgnetic phases, since the Gatrssian critical line does not appear, incontrast to the S :: 172 case. It is exjcected that sonae hidden 22 x Z2 synanaetry bre?tkinghapper?s not only in the Haldane plaase lctrt also in the antif'erronaagnetic one.
