Abstract:

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 Gd0.6Sm0.4Mn2Ge2 compound belonging to the tetragonal RMn2Ge2 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 call be shifted with the change of the Gd and Sm concentration.
