The covariant Lagrangian of the interaction of an electromagnetic field with polarizable spin hadrons has been constructed invoking sequentially the principle of correspondence between relativistic electrodynamics of moving media and relativistic quantum field theory and taking into account the cross-symmetry condition. It has been shown that for 1/2-spin hadrons, to the third order in radiation frequency, the contribution to the effective Lagrangian is from the spin polarizabilities.
