The paper discusses the high-temperature spin-exchange of a mixture of vapors of alkali metals. It is shown that in a small magnetic field, an increase in temperature can lead to a sharp decrease in the frequency of transverse relaxation and to a significant decrease in the frequency of oscillation of the angular moments of atomic sublevels. Such changes in relaxation and frequency are well known in the case of a vapor of a single alkali metal. New in the case of a mixture was the merging of the resonance frequencies of different atoms into one frequency, which is the frequency of rotation of the total angular momentum of the atoms of the mixture. It also turned out that with an increase in temperature, the sign of the g-factors of atoms changes.
