 Title    Ru NMR and NQR Studies in CeRu 2  
 Abstract    We have carried out Ru NMR and NQR measurements in superconductor CeRu 2 having T c = 6.1 K in the temperature range of 1.3-30 K. From the 9y Ru NMR in 10.2 T above H c2 , T{T-const was found in the measured-T range, and the value of T,TK 2 is almost the same as that in the uncorrelated Korringa relation, suggesting that there does not exist the strong spin fluctuation of Ru d-spins. The property of the superconducting state was investigated by using Ru NQR. We observed the Hebel-Slichter peak just below T c and the exponential decrease in 1 /T,, indicating that this superconductivity has an ordinary s-wave character. The effect of Al substitution for Ru was also studied by NMR and NQR.

 Title    Probing the Electronic Structure of Y-Ba-Cu-O Superconductors by Copper NQR/NMR  
 Abstract    The paper discusses some NQR/NMR studies performed on Y-Ba-Cu-O superconductors at the University of Zürich. It is shown how the resonance methods can yield information on electronic properties of quite different character. The review deals with: (1) the temperature and pressure dependence of Cu NQR frequencies in YBa 2 Cu 4 O g (1-2-4); (2) an NQR study of the properties of Ca substituted 1-2-4; (3) the temperature dependence of the Cu Knight shifts in 1-2-4; (4) the NMR of plane Cu2 in the paramagnetic state of YBa 2 Cu 3 0 6 ; (5) the dependence on temperature, pressure and orientation of the Cu spin-lattice relaxation in 1-2-4.
