摘要:

在常压和0.35 K ~室温范围内,用热力学和磁学测量方法研究了Ce $_2$ Rh $_{1-x}$ Pd $_x$ In $_8$固溶体在整个浓度范围内的磁性和超导电性的演化.为此目的,已从In自熔剂中生长出Pd浓度x = 0,0.10,0.15,0.30,0.45,0.55,0.85和1的单晶,并用X射线衍射和微探针分析表征。从反铁磁体Ce $_2$ RhIn $_8$开始,Néel温度随着Pd浓度的增加而逐渐降低,并且$x \ge 0.45$的反铁磁性已经消失。只有Ce $_2$ PdIn $_8$具有超导电性。

英文摘要:

The evolution of magnetism and superconductivity in Ce$_2$Rh$_{1-x}$Pd$_x$In$_8$ solid solutions has been studied within the entire concentration range by means of thermodynamic and magnetic measurements at ambient pressure and at temperatures between 0.35 K and room temperature. For this purpose, single crystals with Pd concentrations x = 0, 0.10, 0.15, 0.30, 0.45, 0.55, 0.85 and 1 have been grown from In self-flux and characterized by x-ray diffraction and microprobe analysis. Starting from the antiferromagnet Ce$_2$RhIn$_8$, the Néel temperature gradually decreases with increasing Pd concentration and the antiferromagnetism has disappeared for $x \ge 0.45$. Superconductivity has been observed only for Ce$_2$PdIn$_8$.
