AbstractSingle crystals of Co1±δCr2∓δSe4 were grown using chemical vapor method with CrCl3 as a transporting agent. Magnetic measurements on the Co1±δCr2∓δSe4 crystals confirm an antiferromagnetic ordering below the Neel temperature of T N = 230 K. Neutron diffraction studies performed on the Co1±δCr2∓δSe4 powder show that the long-range antiferromagnetic ordering is accompanied by a doubling of the c crystallographic axe. For the Co1±δCr2∓δSe4 single crystals electrical resistivity displays an anisotropic behavior: resistivitiy within the (100) plane increases till T N and then decreases as temperature increases. Resistivity in the orthogonal direction increases with temperature with a change in the slope above T N. Muon spin relaxation experiments on the Co1±δCr2∓δSe4 crystals confirm both the long-range magnetic order and ordering temperature established by other techniques.
