Zn-impurity-induced anisotropy reduction of superconductivity is obtained from a resistive transition analysis of single-crystal YBa[sub 2](Cu[sub 1[minus][ital x]]Zn[sub [ital x]])[sub 3]O[sub 7[minus][delta]]. The out-of-plane resistivity ([rho][sub [ital c]]) increases with Zn doping, while the carrier concentration remains almost unchanged. The results are not consistent with the simple Lawrence-Doniach model. Instead, an anisotropic three-dimensional metal model seems to be promising. A Zeeman-contribution-subtracted magnetoresistance analysis indicates that a Zn impurity does not cause any magnetic pair breaking.
