Compositional Dependence of Epitaxial <i>L</i>1<sub>0</sub>‐Mn<sub><i>x</i></sub>Ga Magnetic Properties as Probed by <sup>57</sup>Mn/Fe and <sup>119</sup>In/Sn Emission Mössbauer Spectroscopy
Abstract
<jats:sec><jats:label /><jats:p>The magnetic properties of Mn<jats:sub> <jats:italic>x</jats:italic> </jats:sub>Ga alloys critically depend on composition <jats:italic>x</jats:italic>, and the atomic‐scale origin of those dependences is still not fully disclosed. Molecular beam epitaxy has been used to produce a set of Mn<jats:sub> <jats:italic>x</jats:italic> </jats:sub>Ga samples (<jats:italic>x</jats:italic> = 0.7 ÷ 1.9) with strong perpendicular magnetic anisotropy, and controllable saturation magnetization and coercive field depending on <jats:italic>x</jats:italic>. By conducting <jats:sup>57</jats:sup>Mn/Fe and <jats:sup>119</jats:sup>In/Sn emission Mössbauer spectroscopy at ISOLDE/CERN, the Mn and Ga site‐specific chemical, structural, and magnetic properties of Mn<jats:sub> <jats:italic>x</jats:italic> </jats:sub>Ga are investigated as a function of <jats:italic>x</jats:italic>, and correlated with the magnetic properties as measured by superconducting quantum interference device magnetometry. Hyperfine magnetic fields of Mn/Fe (either at Mn or Ga sites) are found to be greatly influenced by the local strain induced by the implantation. However, In/Sn probes show clear angular dependence, demonstrating a huge transferred dipolar hyperfine field to the Ga sites. A clear increase of the occupancy of Ga lattice sites by Mn for <jats:italic>x</jats:italic> > 1 is observed, and identified as the origin for the increased antiferromagnetic coupling between Mn and Mn at Ga sites that lowers the samples’ magnetization. The results shed further light on the atomic‐scale mechanisms driving the compositional dependence of magnetism in Mn<jats:sub> <jats:italic>x</jats:italic> </jats:sub>Ga.</jats:p></jats:sec>
