In the present note, the stability of stratified Oldroyd viscoelastic fluid in the presence of suspended particles and variable magnetic field in porous medium has been studied. The case of exponentially varying density, viscosity, magnetic field and suspended particles is considered. The system is found to be unstable for the disturbances of all wave numbers for potentially unstable stratification. The effect of variable horizontal, magnetic field has been discussed in the note. The growth rate decreases or increases with the increase in particle density and kinematic viscosity; similarly, the growth rate increases or decreases with an increase in medium permeability and strain retardation time.
