Abstract
The heat capacities of finite chains of magnetic spins , 1, , 2, and with Heisenberg interaction were calculated exactly as a function of temperature. From these data the heat capacities of infinitely long chains were obtained by extrapolation. Further, the antiferromagnetic ground-state energies were estimated.
