Since it appears that the fractional f3 component may be a measure of a surface-rich phase related to relaxation and different from the bulk perovskite, it might influence ferroelectric property of the near-surface region. A systematic correlation between the magnitude of this peak and surface ferroelectric behavior needs to be performed for better understanding of this phase. An interesting point to note is that ion bombardment replaces a with f$ instead of stripping off the outer j3 phase, perhaps due to bombardment-induced restructuring. This is similar to the effect observed on YiBa2Cu3O7-x(YBCO) superconductors.10
