The electrical resistivity and the magnetoresistance have been measured for icosahedral phases of Zn-Mg-RE (RE=Y, Gd). Electrical resistivities of bulk samples of Zn56Mg36Y8, annealed ribbon samples of Zn62Mg30Y8 and annealed ribbon samples of Zn55Mg35.5Gd9.5 are 1 m Ohm cm, 0.3 m Ohm cm and 0.3 m Ohm cm. respectively. The resistivities of all the samples decrease by 5 similar to 7% from 4.2 K to 273 K. At low temperatures, the conductivity of Zn-Mg-Y obeys T-1/2 dependence, while the resistivity of Zn-Mg-Gd obeys ln T dependence, where Gd atoms bear magnetic moments. In Zn-Mg-Y; the magnetoresistance is negative and insensitive to temperature, while in Zn-h Ig-Gd it is positive in a low field range and becomes negative at high field with its magnitude larger at lower temperature. These results are interpreted by the theories of electron-electron interaction, weak localization and s-d exchange interaction.
