Abstract: We have synthesized the intermetallic YPrFe17 compound by arc-melting. X-ray and neutron powder diffraction show that the crystal structure is rhombohedral with R¯3m space group (Th2Zn17-type). The investigated compound exhibits a broad isothermal magnetic entropy change SM(T) associated with the ferro-to-paramagnetic phase transition (TC ≈290 K). The | SM| (≈2.3Jkg−1 K−1) and the relative cooling power (≈100Jkg−1) have been calculated for applied magnetic field changes up to 1.5 T. A single master curve for SM under different values of the magnetic field change can be obtained by a rescaling of the temperature axis. The results are compared and discussed in terms of the magneto-caloric effect in the isostructural R2Fe17 (R = Y, Pr and Nd) binary intermetallic alloys.
