This work was performed using the GPS muon spectrometer at the Swiss Muon Source (SμS) of the Paul Scherrer Institut (PSI), Villigen, Switzerland and we are thankful to the instrument staff for their support. All the μ+SR data was fitted using musrfit [16] and the images involving crystal structure were made using the DIAMOND software. This research was financially supported by the Swiss National Science Foundation (through Project 6, NCCR MaNEP) and Toyota Central Research & Development Labs. Inc. and a Grant-in-Aid for Scientific Research B (No. 20340089) from the MEXT, Japan.

N2 - 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 TN indicatingthe onsetofa long-range order. Above5K, 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 aroundT = 44 K, indicating the onset of short-range 1D correlations.
