【 摘 要 】

Using the magnetohydrodynamic equations with ion gyro-radius corrections, the gravity-driven instability of plasma is analyzed here for the mode which has non zero projection of the wave number along the unperturbed magnetic field. Employing the normal mode technique, the stability analysis had been carried out through the eigen value solution. The suppression of the buoyancy-driven instability in an exponentially stratified semi-infinite plasma layer by the finite Larmor radius effects is shown here.
