<dt>Descripción</dt>
<dd>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 &lt;math&gt;La_2\,\!&lt;/math&gt;&lt;math&gt; CuO_4\,\!&lt;/math&gt;, &lt;math&gt;YBa_2\,\!&lt;/math&gt;&lt;math&gt;Cu_3 O_{7-\delta}\,\!&lt;/math&gt; 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.</dd>
