We study the one-dinuensional S :: l spin systena with interactions up to the next-nearest-neighbor pairs and the single-ion anisotropy and present a case when the system has a plateauhalf the height of the saturated magnetization in the rnagnetization process. In this systetn, theorigin of the plateau is the triplet-dimer state, w'hich has a periodicity different frona that of theHamiltonian, We develop a variational argtrtnent and find that it descrilaes both edges of theplateau well.
