The new type of the working media for thermomagnetic devices is proposed: the intermetallic compounds which have large magnetocrystalline anisotropy and exhibit the spontaneous phase transition from the antiferromagnetic (AF) to ferromagnetic (F) state when the temperature increases above the critical value T_{t}. Moreover, the anisotropy in AF state in the fields below the critical AF-F transition field must be much lower than in the F state. In the present paper the Gd_{0.6}Sm_{0.4}Mn_{2}Ge_{2} compound belonging to the tetragonal RMn_{2}Ge_{2} system is investigated. This compound has the critical temperature T_{t} = 280 K. The thermomagnetic cycle can be realized on the AF-F-AF transition near T_{t2}. The interval of the working temperatures can be shifted with the change of the Gd and Sm concentration.
