Calculations are made of spin specific heat, C' M, , as a function of reduced temperature, kT/J , for Heisenberg open finite chains containing up to 11 ions ( N ≦ 11) with spins S i of 1/2 to 5/2 on the basis of the model described in a preceding communication. Cha‐acteristic features of the C' M ( kT/J ) curves corresponding to various S i ‐ and N ‐values are discussed. These can be used in interpretation of experimental temperature dependences of C' M for the respective ferro‐ and antiferromagnetic chains.
