We report Zn-doping effect in the parent and F-doped LaFeAsO oxy-arsenides.Slight Zn doping in LaFe$_{1-x}$Zn$_{x}$AsO drastically suppresses theresistivity anomaly around 150 K associated with the antiferromagnetic (AFM)spin density wave (SDW) in the parent compound. The measurements of magneticsusceptibility and thermopower confirm further the effect of Zn doping on AFMorder. Meanwhile Zn doping does not affect or even enhances the $T_c$ ofLaFe$_{1-x}$Zn$_{x}$AsO$_{0.9}$F$_{0.1}$, in contrast to the effect of Zndoping in high-$T_c$ cuprates. We found that the solubility of Zn content ($x$)is limited to less than 0.1 in both systems and further Zn doping (i.e., $x$$\geq$ 0.1) causes phase separation. Our study clearly indicates that thenon-magnetic impurity of Zn$^{2+}$ ions doped in the Fe$_2$As$_2$ layersaffects selectively the AFM order, and superconductivity remains robust againstthe Zn doping in the F-doped superconductors.
