An effective strategy of modifying the magnetic properties of iron-rich rare-earth intermetallics is to incorporate small interstitial atoms into the crystal lattice. Besides hydrogen, only boron, carbon, and nitrogen atoms are small enough to enter the structure in this way, and they preferentially occupy interstitial sites surrounded by the largest number of rare-earth atoms. For example, in... 

In the case of normal rare earth intermetallic compounds, it is quite plausible to assume that the rare earth has well-defined 4fn configuration with an oxidation state of +3. Thus the behaviour of the rare earth ion in a metallic system is similar to insulators. The 4/ electrons are strongly correlated in atomic type configurations characterized by total angular momentum quantum levels, J in accordance with Hund s rules. 

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].
