dc.description.abstractEnWe have investigated the hyperfine magnetic interactions between the nuclei of probe <sup>119</sup>Sn atoms in the CaCu<sub>3</sub>Mn<sub>3.96</sub>Sn<sub>0.04</sub>O<sub>12</sub> double manganite by Mössbauer spectroscopy using magnetic measurements. A consistent description of the results obtained in terms of the Weiss molecular field model by taking into account the peculiarities of the local environment of tin atoms has allowed the indirect Cu<sup>2+</sup>-O-Mn<sup>4+</sup> (<i>J</i> <sub>CuMn</sub> ≈ −51 ± 1 K) and Mn<sup>4+</sup>-O-Mn<sup>4+</sup> (<i>J</i> <sub>MnMn</sub> ≈ −0.6 ± 0.6 K) exchange interaction integrals to be estimated. Based on the Kanamori-Goodenough-Anderson model, we show that the magnitude and sign of the intrasublattice exchange integral <i>J</i> <sub>MnMn</sub> correspond to both the electronic configuration of the Mn<sup>4+</sup> cations and the geometry of their local crystallographic environment in the compound under study.
