At 4.2 K an increase in line width indicates small hyperfine fields at the europium nuclei.. Key words: Europium Compounds, Mixed Valence, Magnetism,

The Eu 2+ signal shows a slightly enhanced line width at 4.2 K, indicative of a very small hyperfine field and the onset of magnetic ordering, in agreement with the magnetic data..
