Crystallographic and magnetic studies on iron-rich mixed rare-earth intermetallics (Nd/Tb)2(Fe/Al)17

Magneto-caloric effect in the pseudo-binary intermetallic YPrFe17 compound

“…The crystal structure of the binary intermetallic R 2 Fe 17 compounds can be either of Th 2 Zn 17 -type (rhombohedral R3m space group) for light rare-earths, or Th 2 Ni 17 -type (hexagonal P 6 3 mmc space group) for heavy rare-earths [19,20]. In the case of R = Y, Gd and Tb or in pseudo-binary intermetallic R 2-x R' x Fe 17 alloys with a mixture of two different R atoms, both crystal structures can coexist, with the rare-earths sharing the crystallographic sites [21][22][23][24].…”
