Abstract: | Summary The thermosolutal instability of a rotating plasma in the presence of a uniform vertical magnetic field is studied to include
the effects of Hall current. When the instability sets in as stationary convection for the case of no rotation, the Hall effects
are found to be destabilizing. The stable solute gradient and rotation are found to have stabilizing effects. In the presence
of rotation the Hall currents are found to be stabilizing forT
1>M(1+x)2. the case of overstability is also considered and it is shown that such solutions exist. The variation of the frequency with
respect to the wave number at the neutral state is graphically shown.
