We study the variation of geometric phase with distance for a two spin-1/2 system with Dzyaloshinskii-Moriya (DM) interaction, while one of the spins is driven by a time-varing rotating magnetic field and the other one is coupled with a static magnetic field. It is shown that when we consider the spin-spin coupling coefficient in the form of the Calogero-Moser types, the geometric phase can increase with the distance and reach a peak then it maybe decreases for a short distance and will be unchanged for very long distances. Moreover, increasing the amount of magnetic field causes the decrease of geometric phase in terms of the distance.
