## Abstract The effects of oxygen vacancies and zinc interstitials on the structure and energy of zinc oxide were studied with the semiempirical MO method MSINDO. Cyclic clusters were chosen as model systems. Single and multiple removal of oxygen atoms and zinc interstitials in zinc oxide served to
Zinc-doped -Fe 2 O 3 has been prepared by hydrothermal methods. The zinc K-edge EXAFS and interatomic potential calculations indicate that Zn 2ุ ions substitute for Fe 3ุ ions in the lattice and are accompanied by oxygen vacancies. The 57 Fe MoK ssbauer spectra recorded between 296 and 18 K demonstr
Based on our previously derived z(q, eg) for the t-J model in a spin liquid state, we show that the temperature (T) dependence of the static magnetic susceptibility, Zs (T), of LaE\_xSrxCuO4, over the entire experimentally studied doping (x) range, is in good agreement with our theoretical predictio
