effect of different basic temperature gradients on the onset of Marangoni
ferroconvection is studied. The resulting eigenvalue problem is solved by
Galerkin technique for the lower boundary rigid and either conducting or
adiabatic and the upper boundary at which the surface tension acts is free
adiabatic. The results indicate that the stability of Marangoni ferroconvection
is significantly affected by basic temperature gradients and the mechanism for
suppressing or augmenting the same is discussed in detail. It is found that,
the results obtained under the limiting conditions compare well with the existing
ones.
