Abstract We performed ultrasonic measurements on a quaternary cubic compound PrRu$_{2}$In$_{2}$Zn$_{18}$ to explore the ground state properties derived from non-Kramers $\Gamma_{3}$ doublet of Pr$^{3+}$. PrRu$_{2}$In$_{2}$Zn$_{18}$ is a quaternary derivative of the ternary compound PrRu$_{2}$Zn$_{20}$ that exhibits a structural phase transition at $T_{\rm S} = 138 $K. In PrRu$_{2}$In$_{2}$Zn$_{18}$, the Zn atoms at the 16$c$ site in PrRu$_{2}$Zn$_{20}$ are selectively replaced by In atoms. A monotonic increase was observed in the temperature dependence of elastic constants $C_{\rm L} = (C_{11}+2C_{12}+4C_{44})/3$ and $C_{\rm T} = (C_{11}-C_{12}+C_{44})/3$ in the temperature range around $T_{\rm S}$ to which an elastic softening was observed in $(C_{11}-C_{12})/2$ for PrRu$_2$Zn$_{20}$. The disappearance of the softening indicates that the structural transition in PrRu$_2$Zn$_{20}$ is suppressed by the substitution of Zn ions by In ones with a larger ionic radius. Alternatively, the $C_{\rm T}$ of PrRu$_{2}$In$_{2}$Zn$_{18}$ exhibits a precursor Curie-type elastic softening toward low temperatures being responsible for the non-Kramers $\Gamma_{3}$ ground state. We discuss the ground state and the evolution of the elastic properties of the different single-crystal samples of PrRu$_{2}$In$_{2}$Zn$_{18}$ grown under different conditions.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
