| Résumé: | The all-electron full-potential linearized augmented plane-wave method is used to show that the variation of tetragonality of the L1 MnPt antiferromagnet switches the magnetization from an easy axis to an easy plane. The optimum lattice parameters are obtained and the changing from inplane to out-of plane is explained by a competition between the strong spin orbit coupling and weak magnetization of Pt with the large magnetization and weak spin–orbit coupling of Mn. Finally we present the X-ray magnetic linear dichroism used to investigate the magnetic anisotropy of the antiferromagnet MnPt. |
