An ion flow-induced anomalous phase behavior of plasma crystal is reported in the presence of external magnetic field. The interaction potentials between dust particles are modified near the plasma sheath due to asymmetric ion flow and magnetic field. This modification results in the tuning in coupling strength between the charged dusts as a characteristic of ion flow speed and the strength of external magnetic field. An equilibrium molecular dynamic (MD) simulation is performed based on the interaction potentials. The simulation results are used to study the thermodynamic properties of plasma crystal in both subsonic and supersonic flow regime. The study shows a repulsive Yukawa dominating phase in supersonic regime and a mixed phase of attractive Wake and repulsive Yukawa in subsonic regime of ion flow. The simulation results show an anomaly in phase behavior of plasma crystal in subsonic flow limit. The thermodynamic study confirms the ion flow-induced anomaly in phase behavior and opens up new possibilities in dusty plasma experiment in near future.
