Evolution of magnetic properties and damping coefficient of Co 2 MnSi Heusler alloy with Mn/Si and Co/Mn atomic disorder
Abstract
International audience ; Ferromagnetic resonance has been used to investigate the effect of Mn/Si and Co/Mn atomic disorder on the magnetic properties and dynamic relaxation of Co 2 MnSi Heusler alloy. He + ion irradiation at 150 KeV is used to induce Co/Mn and Mn/Si swap in the initial structure of the material. While Mn/Si disorder is found to show similar magnetic behavior as compared to the L2 1 order, we observe a strong impact of Co/Mn swap on the static and dynamic properties of the alloy. These results are explained with regard to electronic band structure and damping coefficient first-principles calculations showing the modification of the minority-spin density of states at the Fermi energy and local magnetic orbital moment with Co/Mn swap.
