Observed (crosses) and calculated (solid line) diffraction profiles and their difference (bottom solid line) at for with silicon oil added. Top, middle, and lower peak markers relate to , (also marked as ), and MgO, respectively. Inset is the lattice parameters vs silicon oil content.
Temperature dependence of the normalized resistance for pure and silicon oil doped samples. The inset (right) shows in the fields up to for the sample doped with silicon oil.
Field dependence of at 5, 20, and .
Normalized vs (a) and (b) for pure and silicon oil doped .
(a) Field dependence of the volume pinning force of all samples at . The is normalized by the maximum volume pinning force, . (b) FWHM of various diffraction peaks as a function of the amount of silicon oil.
