angular momentum, heated and soluted from below subjected to a transverse uniform magnetic field. For a flat fluid
layer contained between two free boundaries, an exact solution is obtained. A linear stability analysis theory and
normal mode analysis method have been carried out to study the onset of convection. The influence of various
parameters like rotation, solute gradient, magnetization and internal angular momentum parameters (i.e. coupling
parameter, spin diffusion parameter and heat conduction parameter) has been analyzed on the onset of stationary
convection. The critical magnetic thermal Rayleigh number for the onset of instability is also determined numerically
for sufficiently large values of buoyancy magnetization parameter M1 and results are depicted graphically. The
principle of exchange of stabilities is found to hold true for the ferrofluid with internal angular momentum heated
from below in the absence of rotation, coupling between vorticity and spin, microinertia and solute gradient. The
oscillatory modes are introduced due to the presence of the rotation, coupling between vorticity and spin, microinertia
and solute gradient, which were non-existent in their absence. In this paper, an attempt is also made to obtain the
sufficient conditions for the non-existence of overstability.Ferrofluid, Double-diffusive convection, Rotation, Internal angular momentum, Magnetization4352http://jafmonline.net/JournalArchive/download?file_ID=15315&issue_ID=206Sunilsunilnitham@gmail.com`NoDepartment of Mathematics, National Institute of Technology, Hamirpur, H.P. 177 005, INDIA`
