摘要：

Numerical calculations for the magnetization and the specific heat of CsNiF3 are performed by using finite chains with size N less-than-or-equal-to 7 and the linear extrapolation procedure for 1/N --> 0. Except for the lowest temperatures, the theoretical estimates are consistent with the magnetization measurements. Fairly good agreement is also found for the maxima in the excess specific heat but their positions are underestimated.
