摘      要：Lacking structural periodicity of long-range order induces unusual physical properties in metallic glasses (MGs). Specifically, the low-temperature electron transport behavior of MGs has triggered fundamental interest in solid-state physics. MGs exist as strong scattering systems since their electron mean free paths are com? parable to the average interatomic distances . The temperature coefficient of resistivity (TCR, defined as a =(l/p)(8p/8T)) in these systems can be positive or negative depending on their Fermi level positions .
