| description | The manipulation of magnetic characteristics in 2D materials is essential for their utilization in spintronic and magnetic devices. this study was carried out to investigate the doping process involving a single Fe dopant and the co-doping of two Fe impurities at the Pt site within the Pt2Te4 monolayer. The examination revealed that the introduction of a single iron (Fe) atom and a pair of Fe atoms into the non-magnetic semiconductor monolayer of Pt2Te4 leads to magnetic moments measuring 2 µB and 4µB, respectively. The origin of magnetic moments is observed predominantly around Fe-3d orbitals. In the instances of co-doping involving Fe-Fe substitution, four distinct configurations were examined. One of the configurations, specifically FeFe (1), was identified as the most stable due to its minimal energy level. This configuration also demonstrates a ferromagnetic coupling mechanism between the two Fe substitutions, a phenomenon that can be justified by the significant magnetic moment of 4µB. |
