摘要:

本文用μ子自旋旋转和弛豫测量方法研究了非中心对称$f$ -电子金属间化合物CePt $_3$ B $_{1-x}$ Si $_x$的合金化系列。此外,我们包括化学计量的母体化合物CePt $_3$ B的高压磁化调查。从我们的数据中,我们建立的性质的磁基态性质的系列,推导出有序的磁矩作为化学计量的函数和洞察到有序的磁状态的对称性的演变与$x$。因此,我们可以验证的概念,样品系列的行为基本上可以理解的框架内的Doniach相图。此外,我们的研究结果提出了Dzyaloshinskiii-Moriya磁相互作用在相关电子材料中的作用及其对此类材料中磁波动的影响。

英文摘要:

We present a study of the alloying series of the non-centrosymmetric $f$-electron intermetallic CePt$_3$B$_{1-x}$Si$_x$ by means of muon spin rotation and relaxation measurements. In addition, we include a high pressure magnetization investigation of the stoichiometric parent compound CePt$_3$B. From our data we establish the nature of the magnetic ground state properties of the series, derive the ordered magnetic moment as function of stoichiometry and gain insight into the evolution of the symmetry of the ordered magnetic state with $x$. We thus can verify the notion that the behavior of the sample series can essentially be understood within the framework of the Doniach phase diagram. Further, our findings raise the issue of the role the Dzyaloshinskii-Moriya magnetic interaction plays in correlated electron materials, and its effect on magnetic fluctuations in such materials.
