000063190 5203_ $$aSeveral pseudo-binary RxR''2-xFe17 alloys (with R Y, Ce, Pr, Gd and Dy) were synthesized with rhombohedral Th2Zn17-type crystal structure determined from x-ray and neutron powder diffraction. The choice of compositions was done with the aim of tuning the Curie temperature (TC) in the 270 ± 20 K temperature range, in order to obtain the maximum magneto-caloric effect around room temperature. The investigated compounds exhibit broad isothermal magnetic entropy changes, ¿SM (T), with moderate values of the refrigerant capacity, even though the values of ¿SM Peak are relatively low compared with those of the R2Fe17 compounds with R Pr or Nd. The reduction on the ¿SM Peak is explained in terms of the diminution in the saturation magnetization value. Furthermore, the ¿SM (T) curves exhibit a similar caret-like behavior, suggesting that the magneto-caloric effect is mainly governed by the Fe-sublattice. A single master curve for ¿SM/¿SM Peak(T) under different values of the magnetic field change are obtained for each compound by rescaling of the temperature axis.
