Horizontal flux growth as an efficient preparation method of CeRh${}_2$As${}_2$ single crystals

We report on the efficient method of obtaining CeRh${}_2$As${}_2$ single crystals with the use of a bismuth flux growth method in a horizontal configuration. The crystals thus obtained exhibit much sharper phase transitions and distinctly higher characteristic temperatures $T_{\mathrm{c}}$ and $T_0$, compared to previous reports. Moreover, in our numerous attempts, we found this technique to be scalable and repeatable.
