摘要：

The elastocaloric effect, the electrical resistivity and the thermal expansion have been investigated in a quenched sample of Fe49Rh51 alloy. The giant negative temperature change, resulting from a tensile stress of 529 MN/m2 applied to the sample, is found to be 5.17 K. Using the Clapeyron-Clausius equation, the entropy jump and the antiferromagnetism-ferromagnetism transformation latent heat have been determined, the transformation being induced by the tensile stress applied to this alloy.
