Superconducting properties of Pr-based Filled skutterudite PrRu${}_4$As${}_{12}$

T. Namiki, Y. Aoki, H. Sato +5

We report on systematic study of superconducting characteristics and Pr crystalline-electric-field (CEF) levels of filled-skutterudite \pra ($T_{\mathrm{c}}$ = 2.33 K). The temperature…
