Bulk Magnetic Properties of the Fe0.5Mn0.1Al 0.4 Disordered Alloy
Abstract
<p>In this work we present a simulational study of the bulk magnetic properties of the Fe<sub>0.5</sub>Mn<sub>0.1</sub>Al<sub>0.4</sub> disordered system. The magnetization per site, specific heat and magnetic susceptibility were obtained using Monte Carlo simulation. Simulation results were performed in the framework of a random site-diluted 3D Ising model with nearest neighbor interactions, and using a single-spin-flip Metropolis dynamics for equilibration and energy minimization, from which canonical ensemble and configurational averages were computed. In the simulation, atoms were randomly distributed on a body-centered cubic lattice in order to simulate the disorder and crystalline structure as obtained in the arc-melted Fe<sub>0.5</sub>Mn <sub>0.1</sub>Al<sub>0.4</sub> alloy treated at high temperatures for long periods of time and followed by fast quenching. Competitive Fe-Fe ferromagnetic and Fe-Mn and Mn-Mn antiferromagnetic interactions were taken into account, as well as the Al dilutor effect. We conclude that, accordingly with Mössbauer results, the Fe<sub>0.5</sub>Mn<sub>0.1</sub>Al<sub>0.4</sub> system exhibits a reentrant spin-glass behavior below 30 K characterized by a sharp increase of the mean hyperfine field attributed to the magnetic ordering of the Mn sublattice at these temperatures. Additionally, a ferromagnetic to paramagnetic transition at around 300 K was also evidenced.</p>
