  Title Non-Fermi-liquid signatures in stoichiometric Ce7Ru3 at ambient pressure Type Journal Article
  Year 1999 Publication Physica B – Condensed Matter Abbreviated Journal Physica B  
  Volume 259-261 Issue Pages 405-406  
  Keywords  
  Abstract Magnetic (chi(-1) proportional to root T) and thermal (C-p/T proportional to – log T) temperature dependencies of stoichiometric Ce7Ru3 are studied in order to establish whether its low temperature behavior corresponds to that of a non-Fermi-liquid system at normal pressure. Despite its reduced unit cell volume this compound shows a broadened antiferromagnetic transition, which involves only a small fraction of the expected entropy at T = T-n = 0.8 K. Scaling properties of C-p/t = -A log(t) + ETo (with t = T/T-o) under magnetic field (B) are fulfilled with A = 7.2 J and E = 0.07 B. The thermal characteristics of the transition itself are compared with those of other Ce compounds that also exhibit a “Lambda-shape” in the C-p/T(T) dependence around T-n.
