We formulate a self-consistent Hartree-Fock theory for a spin-1 Bose gas at
finite temperature and apply it to characterizing the phase diagram. We find
that spin coherence between thermal atoms in different magnetic sub-levels
develops via coherent collisions with the condensed atoms, and is a crucial
factor in determining the phase diagram. We develop analytical expressions to
characterize the interaction and temperature dependent shifts of the phase
boundaries.
