Description
Long-range magnetic ordering in R2BaNiO5 (R=magnetic rare earth) quasi-one-dimensional mixed-spin antiferromagnets is described by a simple mean-field model that is based on the intrinsic staggered magnetization function of isolated Haldane spin chains for the Ni subsystem, and single-ion magnetization functions for the rare earth ions. The model is applied to new experimental results obtained in powder diffraction experiments on Nd2BaNiO 5 and NdYBaNiO5 , and to previously published diffraction data for Er2BaNiO 5 . From this analysis we extract the bare staggered magnetization curve for Haldane spin chains in these compounds. copyright 1998 The American Physical Society
