Magnetic resonance and related studies in cerium-tin alloy

The results of nuclear magnetic resonance (NMR) and magnetic susceptibility measurements in CeSn3 are presented together with other available data. The magnetic susceptibility of CeSn3 shows a broad maximum around 135 K and a rapid rise below 30 K. The 119Sn Knight shift in CeSn3 in the temperature region 1.2 t o 300 K is not proportional to the bulk susceptibility. The electrical resistivity of CeSn3 shows a T2 term at low temperatures as expected in localised spin fluctuation systems, and the coefficient of the electronic specific heat is also very large. These results suggest sizeable 4f occupation near the Fermi level in CeSn3
