Abstract

Relationships between the magnetic properties and the film structure of Mn/Al multilayers are examined by changing the thicknesses of Mn and Al layers. X-ray diffractions show that the Mn lattice spacing measured vertical to the substrate becomes smaller by increasing the Mn layer thickness or by decreasing the Al layer thickness. Saturation magnetization and magnetic anisotropy vary depending on the change of the Mn lattice spacing. Ferromagnetism and magnetic anisotropy of Mn/Al multilayers are closely related to the strain in the Mn lattice.
