The static dielectric response of relaxors is described by the spherical random bond--random field model, yielding the first Landau coefficient a=a(T), which differs from the usual expression for ferroelectrics. The fourth-order coefficient b is treated as a phenomenological parameter, which is either positive or negative due to the anisotropy of the stress-mediated coupling between the polar nanoreg","authors_text":"Q.
