Growth of the Al-Pd-Re and Al-Cu-Fe single quasicrystals

Abstract

Partial phase diagrams involving Al-Pd-Re and Al-Cu-Fe icosahedral quasicrystals were constructed to grow their single quasicrystals. On the basis of the phase diagrams, Al-Pd-Re and Al-Cu-Fe single icosahedral quasicrystals were grown by a slow cooling method. Electrical resistivity of the Al-Pd-Re single quasicrystals, p, was measured to be 2000∼4000 μΩcm at 300K and 3000∼6000 μΩcm at 2K, revealing negative temperature dependence with a value of P_4.2k/ P_300K smaller than 2.
