  Mono-arsenide CrAs, endures a helical anti-ferromagnetic order transition at~
265 K under ambient pressure. Recently, pressure-induced-superconductivity was
discovered vicinity to the helical anti-ferromagnetic order in CrAs[Wei Wu et
al., Nature Communications 5, 5508 (2014).]. However, the size of crystal grown
via tin flux method is as small as 1 mm in longest dimension. In this work, we
report the single crystal growth of CrAs with size of 1 * 5 * 1 mm3 via
chemical vapor transport method and its physical properties.
