      abstract     = {We present the linear theory of two-dimensional
                      incompressible magneto-Rayleigh–Taylor instability in a
                      system composed of a linear elastic (Hookean) layer above a
                      lighter semi-infinite ideal fluid with magnetic fields
                      present, above and below the layer. As expected, magnetic
                      field effects and elasticity effects together enhance the
                      stability of thick layers. However, the situation becomes
                      more complicated for relatively thin slabs, and a number of
                      new and unexpected phenomena are observed. In particular,
                      when the magnetic field beneath the layer dominates, its
                      effects compete with effects due to elasticity, and
                      counteract the stabilising effects of the elasticity. As a
                      consequence, the layer can become more unstable than when
                      only one of these stabilising mechanisms is acting. This
                      somewhat unexpected result is explained by the different
                      physical mechanisms for which elasticity and magnetic fields
                      stabilise the system. Implications for experiments on
                      magnetically driven accelerated plates and implosions are
                      discussed. Moreover, the relevance for triggering of
                      crust-quakes in strongly magnetised neutron stars is also
                      pointed out.},
