Electronic structure of intermetallic compounds with CsCl structure: NMR relaxation times

NMR relaxation times T1 and T2 at the Sc and La sites have been measured in a series of intermetallic compounds ScB (B=Cu, Ag, Pd, Rh, Ir, Ru) and LaAg. The product (T1T) is constant for temperatures between 30K and 300K. Below 30K an influence of magnetic impurities on the susceptibility and spin-lattice relaxation time measurements has been found. The analysis for the electronic structure is given in terms of local susceptibilities based on these T1 measurements and in terms of a two-band model.
