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 app roximation process, we derive spin-s reliable Neel temperature T-N and reas onable sublattice magnetization unified for 0 less than or equal to T less than or equal to T-N.
