Studies of Knight Shifts and Hyperfine Structure Constants of Tl₂Ba₂CuO_6+y

Abstract:

The Knight shifts and hyperfine structure constants of Tl₂Ba₂CuO_6+y are theoretically studied from the high order perturbation formulas of these quantities for a tetragonally elongated octahedral 3d⁹ cluster. The calculation results reveal good agreement with the observed values. The obvious anisotropies of the Knight shifts can be ascribed to the local tetragonal elongation of the Cu²⁺ site. The results and the local structure of the system are discussed.
