摘要：
We present magnetoresistivity measurements on AlCuFe quasicrystalline thin films from which the temperature dependence of the inelastic scattering time (τie) has been deduced down to 200 mK in the low field limit. We show that τie presents a weak temperature dependence below 4 K (1/τie∼T0.87) which is in close agreement with the theory of Isawa predicting a crossover from a T3/2 to a T regime. Saturation effects as well as a possible shift in dimensionality have also been investigated. © 1995 The American Physical Society.
