| 中文摘要 | We study the anomalous acoustic softening behavior in La68-xCexAl10Cu20Co2 (x=0, 34, and 68) metallic glasses by magnetic susceptibility, thermal expansion, and specific heat at low temperatures. The Ce-based metallic glass exhibits valence fluctuation phenomenon, anomalous thermal expansion and acoustic Gruneisen parameter at low temperatures. And we provide experimental evidence of the existence of strong electron-phonon coupling in the Ce-based metallic glasses by specific heat. The anomalous acoustic and thermal properties are attributed to the valence instability in the metallic glasses. (C) 2010 American Institute of Physics. [doi:10.1063/1.3467516] |
