We report the synthesis of Ni-doped BaFe2Se3 single crystals by using a flux method. X-ray diffraction (XRD) of Ba(Fe1- xNix)2Se3 shows a gradual peak shift with an increase in the nominal Ni- doping rate, x = 0, 0.05, and 0.10, due to a decrease in unit-cell volume. All samples show a spin glass transition, and temperature dependence of magnetic susceptibility shows a negligible change in the spin-glass transition temperature (Tg) with Ni concentration x. The temperature dependence of electrical resistivity for BaFe2Se3 shows an insulating behavior, and the resistivity value at 295 K and the activation energy (Ea) obtained from the Arrhenius plot decrease with increasing x. These results suggest that the Ni doping can be effectively worked as a dopant for electron charge carriers, but is less efficient in controlling the magnetic property, such as spin glass transition, in the BaFe2Se3 compound.
