论文摘要
在本文中，我们提出了有关CECO $ _ {1-x} $ fe $ _ {x} $ ge $ _ {3} $合金的一些特别重要的问题。首先，研究了低于2 K的电阻率，研究至500 mK，以确认临界替代范围X〜0.65周围的非Fermi-liquid行为。其次，已经研究了使用非弹性中子散射，比热和磁敏感的方法研究了晶体电场（CEF）水平的方案。它旨在阐明对父塞科格$ _ {3} $化合物的不同报告，并提供有关整个CECO $ _ {1-x} $ fe $ _ {x} $ ge $ _ {3} $系列中有关CEF的第一个数据。第三，验证了氢化的作用，尤其是在量子临界点（QCP）（x〜0.65）附近的影响。
In this article we present some particularly important issues regarding the CeCo$_{1-x}$Fe$_{x}$Ge$_{3}$ alloys. Firstly, the electrical resistivity below 2 K, down to 500 mK is studied to confirm the non-Fermi-liquid behavior around the critical substitution range x~0.65. Secondly, the scheme of the crystal electric field (CEF) levels has been investigated employing methods like inelastic neutron scattering, specific heat, and magnetic susceptibility. It aims to clarify different reports on the parent CeCoGe$_{3}$ compound and to provide first data concerning CEF in the entire CeCo$_{1-x}$Fe$_{x}$Ge$_{3}$ series. Third, the effect of hydrogenation, especially around the quantum critical point (QCP) (x~0.65) is verified.
