Investigation of the magnetic anisotropy in a series of trigonal bipyramidal Mn( ii ) complexes

| Description | Understanding and controlling magnetic anisotropy at the level of a single metal ion is vital if the miniaturisation of data storage is to continue to evolve into transformative technologies. Magnetic anisotropy is essential for a molecule-based magnetic memory as it pins the magnetic moment of a metal ion along the easy axis. Devices will require deposition of magnetic molecules on surfaces, where changes in molecular structure can significantly alter magnetic properties. Furthermore, if we are to use coordination complexes with high magnetic anisotropy as building blocks for larger systems we need to know how magnetic anisotropy is affected by structural distortions. We have studied a trigonal bipyramidal nickel(II) complex where a giant magnetic anisotropy can be engineered. Using a combination of high pressure X-ray diffraction, computational methods and high pressure magnetic measurements, we show how the magnetic anisotropy is strongly influenced by small structural distortions, in particular the bond angles which determine the magnitude of the magnetic anisotropy. These results demonstrate that the combination of high pressure techniques with computational studies is a powerful tool that gives a unique insight into the design of systems that show giant magnetic anisotropy. |
| Exploitation Route | We have demonstrated that the combination of high pressure techniques with ab initio studies creates a powerful tool that gives a unique insight into the design of systems that show giant magnetic anisotropy. This methodology can be used by other researchers in their design process. |
