  Title Unexpected magnetic behaviour in a singlet crystal field ground state induced by Tb 4f-instability Type Journal Article
  Year (up) 1988 Publication Zeitschrift für Physik B Condensed Matter Abbreviated Journal Z. Phys. B  
  Volume 70 Issue 2 Pages 187-192  
  Abstract The magnetic susceptibility (chi) of Th1-x Tb x alloys (with 5<x<55a/o Tb) in the range of 1 K<T<350K and the specific heat (forx=1.5a/o Tb) for 0.5<T<10 K were measured. A maximum in chi(T) was observed at a temperature which depends on concentration. The crystal field level scheme that fits the specific heat measurements shows two non-magnetic singlets as lowest levels. Such ambiguity is discussed within the framework of the 4f-Tb instability. The results are in agreement with the matrix superconductiveT c decrease. The contribution of the interconfigurational mixing on chi and the specific heat is also discussed.
