Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<p>The defect structure, hyperfine and magnetic properties of Mn<sup>2+</sup>-doped Fe<sub>3</sub>O<sub>4</sub> of the composition Mn<sub>x</sub>Fe<sub>3-</sub><sub>y</sub>O<sub>4</sub>(y=⅔x) are modeled using atomistic and DFT calculations. The atomistic simulations show the substitution of the Mn<sup>2+</sup> ions for Fe<sup>3+</sup> ones at the tetrahedral sites to be energetically favorable than their substitution at the octahedral sites. These Mn<sup>2+</sup> impurities are charge-balanced by the occupation of either Mn<sup>2+</sup> or Fe <sup>3+</sup> ions of interstitial tetrahedral sites. The method of GGA with on-site Coulomb interaction approximation for the exchange-correlation potential is used to calculate the electronic structure, hyperfine and magnetic moments of the structurally most preferred models. The results obtained show the model in which all the Mn<sup>2+</sup> ions substitute for tetrahedral Fe <sup>3+</sup> ions with Fe<sup>3+</sup> ions expelled to interstitial tetrahedral sites to be consistent with the observed experimental trends of the hyperfine and magnetic properties.</p>
