Transport and magnetic properties of electron-doped superconducting cuprates Eu1.85Ce0.15Cu1-y ZnyO4+alpha-delta (ECCZO) with y = 0, 0.01, 0.02 and 0.05 have been studied from electrical resistivity and magnetic susceptibility measurements, in order to elucidate the effect of partially Zn-substitution for Cu to its superconductivity and localization of electron in normal state. It has been found that the onset of the critical temperature (T-c) from electrical resistivity and magnetic susceptibility measurements was observed at 13 K for y = 0 and delta values of 0.095. With increasing Zn concentration, the onset of T-c disappeared, indicating the destruction of super-conductivity properties by Zn. Moreover, 0.01 of Zn substitution for Cu decreased radius of localization of electron (r) in normal state at low temperatures that may related to the evident of stripe-pinning effects by Zn in electron-doped system of ECCZO. Analysis of magnetic susceptibility data in normal state found a Zn-induced local moments in electron-doped high-T-c superconducting cuprates of ECCZO as observed in hole-doped cup-rates.
