Abstract
The Curie temperatures of Y2Ni17 and Dy2Ni17 were observed to vary with hydrostatic pressure at a rate of −0.44 K/kbar. The results for the compounds R2Ni17 were compared with previously reporteddT c/dp data for R2Co17 and R2Fe17 and discussed in terms of simplified collective and localizedd-electron models. The former model suggests that R2Ni17 and R2Co17 are relatively far from the Stoner instability limit, while the compounds R2Fe17 approach very weak itinerant ferromagnetism. The slow pressure variation of the compensation temperature of Dy2Ni17, −0.03 K/kbar, was attributed to the insensitivity of the R-Ni interaction to interatomic spacing.
