摘要：

We report on the adiabatic temperature changes (Delta T) associated with the magnetocaloric and barocaloric effects in a Fe49Rh51 alloy, For the magnetocaloric effect, data derived from entropy curves are compared to direct thermometry measurements. The agreement between the two sets of data provides support to the estimation of Delta T for the barocaloric effect, which are indirectly determined from entropy curves. Large Delta T values are obtained at relatively low values of magnetic field (2 T) and hydrostatic pressure (2.5 kbar), It is also shown that both magnetocaloric and barocaloric effects exhibit good reproducibility upon magnetic field and hydrostatic pressure cycling, over a considerable temperature range.
