Boundary magnetizations of isotropic magnets in open chains

Boundary contributions of the magnetizations of several isotropic magnets, which are generalized antiferromagnetic Heisenberg models in open chains, are evaluated. The boundary magnetization approaches zero logarithmically 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.
