Its structural and magnetic properties are controlled by tuning the composition and the resulting small deviation from stoichiometry. The magnetic in-plane anisotropy depends on the Mn concentration of the sample and can be controlled in both strength and orientation. This control of the magnetic anisotropy allows for growing NiMnSb layers of a given thickness and magnetic properties as requested for the design of NiMnSb-based devices. The growth and characterization of NiMnSb-ZnTe-NiMnSb heterostructures is presented - such heterostructures form an all-NiMnSb based spin-valve and are a promising basis for spin torque devices.}, subject = {Nickelverbindungen}, language = {en} }
