Abstract

We present the temperature dependence of the Magnetic Hyperfine Shift tensors of ¹⁷O nuclei for the sites within the CuO₂ plane (site O(I)) and in the BaO, LaO, SrO plane (O(II) site) in the compounds YBa₂Cu₃O₇, YBa₂Cu₃O_6.65, La_1.85Sr_0.15CuO₄ and Bi₂Sr₂CaCu₂O₈. For O(I) sites, the isotropic part of the tensor reflects the polarisation of the Oxygen 2s orbitals by the neigboring Cu d-holes and the temperature dependence of the susceptibility. We show that in YBa₂Cu₃O_6.65, the spins of the oxygen p-holes have their own degree of freedom above 120 K.
