From the studies of the Cu substituted YBa 2 (Cu 1 \_ M )30-\_ (M=Fe, Co, Ni, Zn) systems, it is concluded that the pair-breaking of the AbriRo~ov ~n~Gor'kov type by magnetic impurities is absent, or very small if it exists, both on the C(l) and Cu(2) sites. The Hall coefficient is measured for the

The existence of local moments in both Zn-and Ni-doped YBa2Cu408 (Y1248) is confirmed by a Curie-law T-dependence of NMR linewidth and the Cu relaxation at low T. The reduction of Cu-NQR signal intensity in Ni-doped Y1248 suggests that, in contrast to the case of Ni-doped YBa2Cu30 7 (Y1237), the Cu
In a recent paper [S. B. Ogale et al., Solid State Commun 89 (1994) 1] we reported that the superconducting transition temperature (T c) is suppressed drastically in YBa2Cu30 7\_ d (YBCO) doped simultaneously with Fe and Zn as compared to an equivalent total doping of Zn or Fe, on the higher side of
