- Аннотация: The temperature dependences of initial magnetic permeability, specific heat capacity and magnetocaloric effect in annealed and quenched samples of Fe48Rh51 alloys near the antiferromagnetic-ferromagnetic (AF-F) first-order phase transition have been investigated. The application of a magnetic field of about 2 T to a quenched sample of this alloy at 308.2 K causes a temperature drop of 12.9 K under adiabatic conditions. The magnetocaloric temperature changes were combined with zero-field specific heat data to construct T-S and T-Δ(Sm = Se) diagrams for various heat-treated samples of Fe49Rh51 alloys and on the basis of these diagrams the refrigerant capacity of alloys was evaluated. The value of the refrigerant capacity of a quenched sample of the alloy at a field of 1.95 T is 135.22 J kg-1 T-1. This value is significantly greater than the refrigerant capacities of well known magnetocaloric materials. The possibility of using the AF-F transition in FeRh alloys for magnetocaloric refrigeration is assessed. © 1992.
