- Abstract
Single‐crystalline antiferromagnetic artificially layered [Ni/Mn] films of different thicknesses, covered by ferromagnetic Co layers, are deposited on Cu3Au(001). Their structural and magnetic properties are characterized by low‐energy electron diffraction (LEED) and magneto‐optical Kerr effect, respectively, and compared with disordered NixMn100−x alloy films with the same Ni/Mn ratio and the same film thickness. LEED intensity‐versus‐energy curves show that the perpendicular interatomic lattice distance is decreased in the artificially layered [Ni/Mn] samples in comparison to the disordered NixMn100−x alloy films. At the same time, the artificially layered [Ni/Mn] films exhibit higher coercivity and exchange bias of the adjacent Co layer compared to those of NixMn100−x/Co. This is discussed as a consequence of the different interatomic lattice distance, presumably caused by an ordered buckling in the artificially layered [Ni/Mn] samples, leading to a stronger interlayer exchange coupling.
