Abstract
Finite-size effects in a spin-(Formula presented) one-dimensional (1D) Heisenberg antiferromagnet (HAF) are studied experimentally and theoretically. The calculated susceptibility is compared with that observed in the quasi-1D HAF (Formula presented). Excellent agreement between theory and experiment is obtained without any adjustable parameters above about (Formula presented), where (Formula presented) is the dominant exchange interaction constant.
