✦ Synopsis

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 reliable Neel temperature T and reasonable sublattice magnetization unified for ´N 0 F T F T .
