摘要: We have extended, from order 12 through 25, the high-temperature series expansions (in zero magnetic field) for spin-spin correlations of spin-S Ising models on square, simple-cubic and body-centered-cubic lattices. On basis this large set data, we confirm accurately validity scaling universality hypotheses by resuming several tests which involve correlation function, its moments exponential or second-moment correlation-lengths.
