Abstract

The magnetic properties of a monolayer of Mn₁₂ single molecule magnets grafted onto a silicon (Si) substrate have been investigated using depth-controlled β-detected nuclear magnetic resonance. A low-energy beam of spin-polarized radioactive ⁸Li was used to probe the local static magnetic field distribution near the Mn₁₂ monolayer in the Si substrate. The resonance line width varies strongly as a function of implantation depth as a result of the magnetic dipolar fields generated by the Mn₁₂ electronic magnetic moments. The temperature dependence of the line width indicates that the magnetic properties of the Mn₁₂ moments in this low-dimensional configuration differ from bulk Mn₁₂.
