Enhanced magnetocaloric effect in rapidly solidified HoNi2 melt-spun ribbons

“…The results obtained are compared with those previously reported for bulk polycrystalline samples. This processing technique has been recently applied to fabricate ribbon samples of other Laves phases of the same family, such as TbNi 2 and DyNi 2 with R = Tb or Dy [15,16], with positive results.…”

Effect of Cu doping on the magnetic and magnetocaloric properties in the HoNiAl intermetallic compound

“…The MCE was generally characterized by the iso- Table 2. It was evident that the peak values of DS M were competitive to the other potential magnetic refrigerant materials in low temperature span under the same field changes [29][30][31][32][33][34][35][36][37]. For practical application, particular attention should be paid that large DS values as À12.3 and À9.4 J/kg K with corresponding RC of 80 J/kg and 79 J/kg could achieved for a low field change of 0-20 kOe, which could be supplied by Pr 2 Fe 14 B permanent magnet.…”

Magnetism and magnetocaloric effect of melt-spun, nanostructured GdAl2

“…These compounds exhibit large magnetocaloric effect near their ferromagnetic ordering temperatures [5]. Recent studies on melt-spun rare earth intermetallic compounds such as RNi, RNi 2 , and RCu 2 [6][7][8] have revealed micro-granularity and preferred orientation while polycrystalline nature of the samples was preserved. Most-importantly, the melt-spun samples displayed comparable magnetocaloric effect with the corresponding arc-melted samples.…”
