  Title The critical pressure of chromium Type Journal Article
  Year 2008 Publication Physica B: Condensed Matter Abbreviated Journal Physica B  
  Volume 403 Issue 5-9 Pages 1222-1224  
  Keywords Chromium; Quantum phase transitions; High pressure; Resistivity  
  Abstract We present first results of high-pressure resistivity measurements on pure chromium. Two pieces of evidence show that spin density wave magnetism is suppressed at a critical pressure pc?10GPa, namely, the evolution of the ordering temperature TN(p) and the rapid decrease of the residual resistivity close to pc. Our discussion profits from the comparison between pressurized-Cr and the Cr1-xVx alloy, for which a large amount of information on its electronic properties is available.

  Title Multiprobe high-pressure experiments in CePd0.6Rh0.4 and CePd3 Type Journal Article
  Year 2009 Publication Physica B: Condensed Matter Abbreviated Journal Physica B  
  Volume 404 Issue 19 Pages 2898-2903  
  Keywords Ce compounds; Ferromagnetism; Quantum phase transition; High pressure; Resistivity; Seebeck coefficient; Specific heat  
  Abstract Results of recent multiprobe high-pressure experiments on ferromagnetic CePd0.6Rh0.4 and intermediate-valent CePd3 are presented. Simultaneous resistivity (ρ), thermopower (S), and ac heat capacity measurements show that the long-range ferromagnetic state of CePd0.6Rh0.4 vanishes in the proximity of a sharp valence-crossover pressure , i.e. before reaching a quantum critical point. However, a magnetic signal that is progressively suppressed is still detected at higher pressures. For CePd3, the results of simultaneous ρ(T,p) and S(T,p) measurements up to and down to the mK temperature range show a surprisingly weak pressure dependence.
