N2 - The drift wave instability driven by the parallel ion flow velocity shear is observed to be anomalously suppressed by superimposing light potassium (K) and heavy cesium (Cs) ions in the magnetized plasma. In addition, the shear strength which yields the peak of the fluctuation amplitude becomes larger with an increase in the superimposed K or Cs ion density. These phenomena are considered to be caused by enhancement of the ion Landau damping effect due to a mixture of the unequalmass ion species.
