The temperature and Zn concentration dependence of the electrical resistivity, specific heat, magnetic susceptibility, and electron paramagnetic resonance (EPR) spectra of YBa/sub 2/(Cu/sub 1-x/Zn/sub x/)/sub 3/O/sub 7-y/ with y approx. 0.1 has been measured for x less than or equal to 0.16. In addition, the temperature and field dependence of the magnetization has been measured for 20) and /rho/ increases gradually with increasing Zn content. However, for x less than or equal to 0.10, /rho/(T) becomes semiconductor-like, with a very rapid increase of the resistivity with increasing x. The electrical resistivity, magnetic susceptibility, EPR spectra, and specific heat all indicate that the d-holes associated with the Cu ions become localized in the nonsuperconducting phase, x less than or equal to 0.10.
