摘要：
The finite-size scaling function of the nonlinear susceptibility of the ferromagnetic Heisenberg chain is given explicitly. It is conjectured that the scaling function is universal for any values of S. The conjecture is based on the exact solution of the nonlinear susceptibility for S=infinity, and numerical calculations for S=1/2 and S=1.
