Kondo-like magnetic scattering in electrical transport of Al 70-x B x Pd 20 Mn 10 (x  =  0, 0.5, 1, 2 and 4) quasicrystals.

The electrical conductivity and magnetization behaviour of single-phase Al 70-x B x Pd 20 Mn 10 (x?=?0, 0.5, 1, 2 and 4) quasicrystals have been measured. We observe that boron substitution for aluminium causes large changes in the s vs. T behaviours. s vs. (ln?T) -1 plots shows linear behaviour. Scaling was achieved by plotting {(s(T)?-?s min )/(s 4 ?-?s min )} vs. [ln(T/T min )] -1 . These samples show large positive magnetoresistance with H 2 behaviour. In the Al–B–Pd–Mn and Al–Pd–Mn quasicrystals, the observed s(T) behaviour has been explained using the weak localization theory, including Kondo-type spin-flip scattering and not due to spin-orbit scattering.
