Descrição: The hyperfine interactions in Fe substituted copper oxide ternary and quaternary compounds with perovskite-related structures are studied, using the Local Density theory in an embedded cluster approach. The self-consistent electronic structure is examined for Cu and Fe sites in a number of plausible local: geometries representative of <math>La_2\,\!</math><math> CuO_4\,\!</math>, <math>YBa_2\,\!</math><math>Cu_3 O_{7-\delta}\,\!</math> and related materials. Mössbauer isomer shifts, electric field gradients, magnetic moments, and contact hyperfine fields are presented for comparison with experiment and discussed in light of lattice structure data.
