EuCl$_3\\cdot 6$H$_2$O is a promising solid-state platform for such searches. The narrow inhomogeneous linewidth of the Eu optical $^7\\hspace{-0.1em}F_0 \\leftrightarrow\\,^5\\hspace{-0.1em}D_0$ transition in this material opens the opportunity to optically pump the $^{153}$Eu nuclear spin ensemble into a single hyperfine sublevel.
