Single crystals of and were grown from CuAs and CuSb self-flux, respectively. The crystallographic, magnetic, thermal, and electronic transport properties of the single crystals were investigated by room-temperature x-ray diffraction (XRD), magnetic susceptibility versus temperature , isothermal magnetization versus magnetic field , specific heat , and electrical resistivity measurements. crystallizes in the body-centered tetragonal -type structure (space group ), whereas crystallizes in the related primitive tetragonal -type structure (space group ). The energy-dispersive x-ray spectroscopy and XRD data for the crystals showed the presence of vacancies on the Cu sites, yielding the actual composition . The and data reveal metallic character for both and . Antiferromagnetic (AFM) ordering is indicated from the , and data for both ( K) and ( K). In , the ordered-state and data suggest either a collinear A-type AFM ordering of spins or a planar noncollinear AFM structure, with the ordered moments oriented in the tetragonal plane in either case. This ordered-moment orientation for the A-type AFM is consistent with calculations with magnetic dipole interactions. The anisotropic and isothermal data for , also containing spins , strongly deviate from the predictions of molecular field theory for collinear AFM ordering and the AFM structure appears to be both noncollinear and noncoplanar.
