Single crystals of PrCo₂ have been grown from flux starting from Pr_0.44Co_0.56 that was synthesized by arc melting of stoichiometric mixtures of the elements. The Pr_0.44Co_0.56 ingot was loaded in a Boron Nitride (BN) crucible and sealed inside a quartz tube under vacuum. The quartz ampoule was heated to 1203 K, and then slowly cooled down to 923 K at a rate of 2 K/h. The obtained crystals have octahedral shapes and are of cubic C15 Laves phase structure confirmed by room temperature powder and single-crystal X-ray diffraction measurements. Magnetic susceptibility data show the Curie temperature T_C = 46.7 K. The experimental value of saturation magnetization M_s = 3.2 μ_B/f.u is consistent with our theoretical calculations.
