Transport in the Al 71 Pd 21 Mn 8− X Re X Quasicrystalline System

In an effort to understand the effects of a quartenary element introduced into a ternary quasicrystalline system, quartenary Al 7 1 Pd 2 1 Mn 9 - X Re X quasicrystals were grown, where X had values of 0, 0.08, 0.25, 0.4, 0.8, 2, 5, and 8. X-ray data confirm that the addition of a fourth element does not alter the quasiperiodicity of the sample. Because electronic transport is governed by different mechanisms in the parent systems (Al 7 1 Pd 2 1 Mn 8 and Al 7 1 Pd 2 1 Re 8 ), electrical and thermal transport measurements in the alloyed system have been performed on these samples and are presented here.
