Two‐Time Spin‐Pair Correlation Function of the Heisenberg Magnet at Infinite Temperature. III. bcc Lattice and Arbitrary Spin

The expansion coefficients in powers of time of the two‐time spin‐pair correlation function are obtained up to terms of order t8 for the bcc Heisenberg magnet of spin ½ at infinite temperature and up to terms of order t6 for the linear, square, sc, and bcc Heisenberg magnets of an arbitrary spin at infinite temperature. The result is applicable to the isotropic as well as the anisotropic Heisenberg magnet where the exchange integrals in the z direction and in the orthogonal plane are assumed to be different. Analysis of the results are given in separate articles.
