摘要：

High-temperature power-series expansions for the free energy of a classical Heisenberg ferromagnet in an applied field are given in the form -FNkT=n,la2 n,lh2nxl, where h=gβHk T and x=Jk T. The coefficients are given for l≤7 and 4≤2n≤10. Estimates of the critical exponents for the fourth to tenth field derivatives of F are given. © 1968 The American Physical Society.
