Many models have been postulated to account for the interconfiguration fluctuations (ICF) in rare earth intermetallic compounds. We will consider Hirst s model which assumes that the 4/ electrons are highly correlated and preserve their atomic-like features during the valence fluctuation. Both the X-ray photoelectron spectra and the magnetic susceptibility of rare earth intermetallic compounds can be successfully explained on the basis of Hirst s model [8,11]. 

According to the model the period r of the interconfigurational fluctuation is given by the width, d ( hr) of the principal band. The average valence V is given by...

More precise statements regarding the validity of a homogeneous model were presented by Maple and Wohlleben (37), whose susceptibility measurements showed that metallic SmS under pressure behaves very similarly to SmB6 at atmospheric pressure. The concept of interconfiguration fluctuations , first proposed by Hirst (38) in...
