“…In general, crystals grow as rectangular plates in flux. However, growths with a maximum temperature of 1000 We have also grown crystals by chemical vapor transport with I 2 , a technique frequently employed for CoAs and other 1:1 3d metal arsenides [17][18][19][22][23][24][25][26] . In this case the procedure is to combine prereacted CoAs powder with about 3 mg/mL of polycrystalline I 2 in an evacuated quartz ampule of length 15 cm and place the ampule in a horizontal tube furnace.…”

Transition metal-pnictide compounds have received attention for their tendency to combine magnetism and unconventional superconductivity. Binary CoAs lies on the border of paramagnetism and the more complex behavior seen in isostructural CrAs, MnP, FeAs, and FeP. Here we report the properties of CoAs single crystals grown with two distinct techniques along with density functional theory calculations of its electronic structure and magnetic ground state. While all indications are that CoAs is paramagnetic, both experiment and theory suggest proximity to a ferromagnetic instability. Quantum oscillations are seen in torque measurements up to 31.5 T, and support the calculated paramagnetic Fermiology. arXiv:1802.04768v2 [cond-mat.str-el]

“…However, the single crystals were as small as about 0.15 × 1 × 0.15 mm 3 , which hinders some further physics measurements. Another monoarsnide, FeAs has been grown successfully via chemical vapor transport (CVT) method [16]. Therefore, it is worthy to try to grow CrAs single crystal via CVT method.…”

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 mm 3 via chemical vapor transport method and its physical properties.

“…3(a), for sample 2F025-24 and 2N025-24, the ZFC and FC curves are separated above T c . This separation may be caused by magnetic impurities such as FeAs [32]. Sample 1A025-24 prepared by As 2 O 3 powder has the highest T c of 51.3 K. Sample 2F025-24 prepared by Fe 2 O 3 powder has the lowest T c of 35 K. In Fig.…”
