EXTENDED HIGH-TEMPERATURE SERIES FOR THE N-VECTOR SPIN MODELS ON 3-DIMENSIONAL BIPARTITE LATTICES

High-temperature expansions for the susceptibility and the second corr elation moment of the classical N-vector model [O(N) symmetric Heisenb erg model] on the sc and the bcc lattices are extended to order beta(1 9) for arbitrary N. For N = 2, 3, 4,... we present revised estimates o f the critical parameters from the newly computed coefficients.
