Abstract
Low-temperature magnetic properties of YbDx cubic deuteride phase are repor ted and interpreted in the model of intermediate valence system with the gr ound state consisting of two narrow quasiparticle bands located at the Ferm i level. The estimated bandwidth, Gamma = 0.3 meV and the gap value, Delta = 1.35 meV for YbD2.67 will reproduce the shape of broad maximum in magneti zation at around 4.5 K. (C) 1999 Elsevier Science B.V.
