Among rare-earth based pnictides with CaAl2Si2 type crystal structure there are some copper containing compounds, however data on their physical properties are limited [1]. In this report we present at the first time the crystal structure, electric and magnetic properties of two compounds – YbCuZnAs2 and YbCuZnSb2. Crystals of YbCuZnAs2 and YbCuZnSb2 were synthesized by solid-state-reaction of the constituting elements in evacuated fused quartz tubes at 11000C. The crystal stoichiometry was evidenced by energydispersive X-ray analysis. X-ray powder diffraction (XRD) (for YbCuZnAs2) and X-ray single-crystal data (for YbCuZnSb2) were used to determine the crystal structure. The electrical resistivity was measured by the 4-probe dc technique in a temperature range of T=10-300 K. The data on magnetic susceptibility were obtained using a commercial SQUID magnetometer (MPMS). According to the X-ray diffraction data both compounds obey the trigonal CaAl2Si2 type crystal structure (space group P-3m1; No. 164). The unit cell parameters are a=4,093Å, c=6,711Å for YbCuZnAs2 (powder diffraction, obtained by Rietveld analysis) and a=4,4394(1) Å, c=7,4139(3) Å for YbCuZnSb2 (single crystal data). The temperature dependence of the resistivity for both compounds shows a metallic character. The Seebeck effect measurements in the YbCuZnAs2 sample indicate an n-type conductivity at room temperature, whereas the YbCuZnSb2 samples were of p-type. The magnetic susceptibility of YbCuZnAs2 shows a Curie-Weiss behavior for T=10-300K with a negative paramagnetic Curie temperature Θ = -213K and an effective magnetic moment μeff = 0.05 μB/Yb ion. Weak paramagnetic and weak diamagnetic contributions were observed for the YbCuZnSb2 samples for different probes from one ingot. From the electron formula Yb2+Cu2+Zn2+{As(Sb)3}2 the presence of divalent Yb ions in both YbCuZnAs2 and YbCuZnSb2 should be expected. Considering the fact that the theoretic magnetic moment for Yb2+ (4f14) is 0 μB, the very weak magnetism observed in YbCuZnAs2 and YbCuZnSb2 confirms that all Yb ions have a valency 2+. The observed small magnetic signals can be explained by the presence of minor magnetic impurities, such as Yb2O3 or YbAs.
