Abstract

We study the spin-$s$ quantum Heisenberg antiferromagnetic models in a magnon theory free of any unphysical magnon state. Because the unphysical magnon states are completely removed in the magnon Hamiltonians and during the approximation process, we derive spin-s (s>1/2) reliable Neel temperature $T_N$ and reasonable sublattice magnetization unified for $T\leq T_N$.<br />4 papges with 2 figures included, revtex
