The paramagnetic resonance studies of Co²⁺ ions in Mg_2.997Co_0.003V₂O₈ single crystals are reported. The single crystals of Mg_2.997Co_0.003V₂O₈ were grown from polycrystalline feed rods by floating zone technique. This compound have the same (Cmca) crystal structure and very similar lattice parameters to the kagome staircase compound Co₃V₂O₈. The EPR measurements were carried out using Bruker EMX spectrometer working on fixed frequency (9.25 GHz) with Oxford-made helium flowing cryostat in temperature range from 3.8K to 300K. The samples were the roentgenographically oriented disks of 3 mm diameter and thickness of 0.5 mm cut from the single crystalline rod. The EPR spectrum shows two groups of resonance lines associated with two crystallographically nonequivalent Co ions positions that are known in the kagome staircase system as "cross-tie" and "spine" sites. The ground state was described by spin-Hamiltonian with an effective electronic spin S=1/2 and nuclear spin I=7/2. The local symmetry of oxygen octahedron surrounding Co ions, main values of the g-factors and hyperfine structure were determined for both cobalt positions.
