We report theoretical and numerical results on convection for a magnetic fluid in a
viscoelastic carrier liquid. We focus in the stationary convection for idealized boundary
conditions. We obtain explicit expressions of convective thresholds in terms of the control
parameters of the system. Close to bifurcation, the coefficients of the corresponding
amplitude equation are determined analytically. Finally, the secondary instabilities are
performed.
