Change of the Yb valence in YbTMAl compounds

Description
Summary:We present an investigation of YbTMAl phase diagrams with TMPd, Ag and Au. Several new compounds have been characterized by measurements of the magnetic susceptibility, the electrical resistivity and, in some cases, the specific heat. It seems that the crossover from the stable-trivalent to the intermediate-valent behavior occurs much more abruptly in Yb- than in Ce-based compounds on changing the composition. A comparison of the CeTMAl compounds with their Yb homologs suggests that replacement of Ce by Yb in an intermediate-valent Ce compound and in a trivalent Ce compound results in an Yb 3+ and in an Yb 2+ state, respectively.
