The BaCO₂V₂O₈ compound belongs to a wide group of quasi-one-dimensional (Q1D) antiferromagnets (AF) and its Co²⁺ ions form Q1D screw-chains along the c-axis. We here present the first investigation of the microscopic magnetic nature of a single crystalline BaCO₂V₂O₈ sample using μ⁺SR. Our data reveal the presence of several clear muon frequencies below T_N indicating the onset of a long-range order. Above 5 K, the μ⁺SR spectra is well fitted to a simple power-exponential relaxing function. The temperature dependence of the relaxation-rate (λ) as well as the power (n) display a clear anomaly around T = 44 K, indicating the onset of short-range 1D correlations.
