摘要：

We investigated the electrical resistivity and the magnetism of heavy-rare-earth-based Zn(60)Mg(30)Ho(10) F-type icosahedral quasicrystals in the temperature region between 2 K and room temperature below 80 kOe in magnetic field. The maximum value of the electrical resistivity is 159 mu Omega cm which is comparatively lower than other quasicrystal systems. Below 15 K, the magnetic-field dependence exhibits a magnetoresistance maximum which has not been observed in quasicrystals studied to date, and the temperature dependence shows a resistance minimum. The temperature dependence of the magnetic susceptibility follows, a Curie-Weiss law between 10 K and room temperature corresponding to the effective number of Bohr magneton 10.6 for every Ho atom in the sample. The earlier mentioned anomalies are considered to be related to the dense and large magnetic moments located at the quasiperiodic lattice. (C) 1998 Elsevier Science Ltd. All rights reserved.
