Abstract
The system Yb1-xInxCu2 exhibits a first order valence phase transition of the Yb ion. Partial substitution of Yb by Eu or Gd increases and decreases the valence phase transition temperature respectively. While the divalent Eu exhibits spin glass phenomena (TG (0) ˜ 20 K), the trivalent Gd stays paramagnetic down to 4.2 K.
