• The effect of the finite Larmor radius (FLR) of ions on the thermal instability of a plasma in porous medium is investigated. The case with vertical magnetic field is discussed. It is found that the presence of finite Larmor radius and magnetic field introduces oscillatory modes which otherwise do not exist. When the instability sets is as stationary convection, the finite Larmor radius is found to have a stabilizing effect. The medium permeability has destabilizing or stabilizing effect under certain condition in the presence of FLR effect whereas in the absence of FLR effect the medium permeability always has destabilizing effect. Similarly, magnetic field has stabilizing or destabilizing effect under the same above condition in the presence of FLR effect whereas in the absence of FLR effect, magnetic field always has stabilizing effect and medium permeability has destabilizing effect.
