Abstract: This paper reports on the-structural and magnetic properties of tau MnAl/Co superlattices epitaxially grown on AlAs/GaAs by Molecular Beam Epitaxy. In tau MnAl/Co superlattices with Co layer thickness < 8 Angstrom, a strong anti-ferromagnetic coupling between the ferromagnetic tau MnAl and Co layers is found, as well as the presence of a large perpendicular magnetic anisotropy in both constituent layers, resulting in an unusually abrupt spin reversal at high fields. When increasing the Co layer thickness, the shape anisotropy in the Co layers dominates this AF coupling and the constituent layers display different magnetization directions: perpendicular (tau MnAl) and parallel (Co) to the growth plane.
