Abstract
Boundary contributions to the magnetizations of several isotropic magn ets, which are generalized antiferromagnetic Heisenberg models in open chains, are evaluated. The boundary magnetization approaches zero log arithmically as the external field goes to zero, in each of the models , namely the spin-S Takhtajan-Babujian model and the SU(N) Heisenberg model.
