| description | •Pseudo-binary of bulk Pr2Fe17−xAlx intermetallics alloys have synthesized.•The influence of Al substitution for Fe on the structural and magnetic properties of Pr2Fe17−xAlx compounds was investigated.•The temperature dependence of the magnetization, the magnetic entropy change, as well as the relative cooling power around the second-order magnetic transition for the alloys are reported.
The structural and magnetic properties of the Pr2Fe17−xAlx (x=0, 0.25, 0.5, 0.75, 1) compounds synthesized by arc-melting were investigated. The X-ray diffraction (XRD) coupled with the Rietveld analysis indicate that all samples are single phase with the rhombohedral Th2Zn17 type structure. Moreover, it reveals a 6c preferential occupation for the substituting element Al atoms in R3¯m. The unit cell volume increases slightly with increasing aluminum content while the c/a ratio remains constant. The study of magnetic properties reveals that Curie temperature increases with the Al content. The magnetic entropy change ΔSM was estimated from isothermal magnetization curves and it decreases with the increase of Al content from 5.5Jkg−1K−1 (x=0) to 4.2Jkg−1K−1 (x=1) at μ0H=5T. The saturation magnetization Ms, the magnetocaloric effect (MCE) of the compounds and the relative cooling power (RCP) were determined by measuring their magnetic properties. |
