Abstract
We report an inelastic neutron scattering study (INS) on the low-energy crystal electric field (CEF) excitations of Pr(2-x)Sr(x)NiO(4+delta )single crystals at various temperatures. The observed low-E CEF level of the 0-doped sample (x = 0, delta approximate to 0.24) at similar to 5.5 meV appears at significantly lower energy than that of the Sr-doped sample (x = 0.5, delta = 0.0) at similar to 8.5 meV. Applying the point charge (PC) model calculation, this has been interpreted as an effect of the interstitial oxygen via lowering the local symmetry and modifying the CEF environment of the central rare earth Pr3+ ((3) H-4) ions.
