We measured the magnetic susceptibility , electrical resistivity , and specific heat of a sputtered amorphous (a-)CeRu 2 Al 10 alloy. value for a-CeRu 2 Al 10 alloy follows a Curie-Weiss paramagnetic behavior in the high-temperature region, and magnetic transition was not observed down to 2 K. The effective paramagnetic moment eff is 1.19 /Ce-atom. The resistivity shows a typical disordered alloy behavior, that is, small temperature dependence for the whole temperature range. We observed an enhancement of and / in the low-temperature region of < 10 K. The enhancement in is suppressed by applying a magnetic field. It is suggested that this behavior is caused by the Kondo effect.

The low temperature specific heats of (Fe0.5Co0.5)72B20Si4Nb4 amorphous and crystallized alloys are measured and analyzed from 1.4 to 110 K. Specific heats can be well fitted by electronic and phonon contribution terms. It is found that the electronic contribution term in specific heat for amorphous alloy is larger than that for crystallized one, and this phenomenon has been interpreted in detail. The research shows that the electronic density of states at the Fermi level and the localized loose “rattler” atoms in oversized cage structure may make contributions to the enhancement of electronic specific heat coefficient γ, and result in a larger electronic contribution term. This study is significant for further understanding the structure–property relationship for amorphous alloys at low temperature.

“…The expression of θ D and θ E can be unified as where ℏ is the reduced Planck constant, ω i (i = D, E) the vibration frequency of Debye oscillator and Einstein oscillator respectively, and k B the Boltzmann constant. Similarly, the vibration frequency in MGs is expressed based on the simple harmonic vibration model as [20] …”
