Query: Compressible spherical dipolar glass model of relaxor ferroelectrics   The interactions between the dielectric polarization and the fluctuations of
the strain (stress) tensor in relaxor ferroelectrics are shown to give rise to
the anisotropy of the anharmonic P4-term in the Landau-type free energy,
however, the harmonic P2-term is still properly described by the rigid
spherical random bond--random field model. These are the essential features of
the compressible spherical dipolar glass model, which is used to calculate the
singularities of the specific heat near field-induced critical points. The
results agree with recent high-resolution calorimetric experiments in PMN
[110].
