Local magnetometry using miniature Hall-probe array was used to study vortex distribution in superconducting single crystal of CuxTiSe2, with x=0.064 and Tc=3.2 K. We show that vortices after penetration into the sample move towards the center, resulting into a dome-shape field profile. Such a profile is a signature of relatively low pinning. We show that these measured profiles are consistent with a model proposed for the samples in the absence of bulk pinning. Modifications necessary to obtain quantitative agreement between the model and the data are presented.
