Acesso em:.https://bdm.ufpa.br/jspui/handle/prefix/7070There is a wealth of experimental information available regarding the electronic and mag netic properties of Fe-based alloys. Understanding the microscopic origins of these proper ties, particularly the correlated magnetic interactions, is crucial for describing the stability of these alloys and contributing to advancements in the field of Materials Physics, such as magnetocaloric and ultrafast magnetization dynamics. In this study, we performed first-principles calculations using the Real Space - Linear Mun-Tin Orbital – Atomic Sphere Approximation (RS-LMTO-ASA) method to investigate the nature of exchange coupling (Jij) in diluted Fe alloys. Thus, we computed the electronic structure and the impurity exchange interaction of Sc, V, Ta, Cr, Mn, Fe, Co, Ni, and Pd when embedded in the Fe bcc matrix. Additionally, we analyzed the contribution of the first neighbors Eg and T2g orbitals.Acesso AbertoMagnetismoImpurezasInteração de trocaCNPQ::CIENCIAS EXATAS E DA TERRA::FISICATrabalho de Curso - Graduação - Monografia
