This proposal aims to identify novel strategies for preparing better single-molecule magnets. Single-molecule magnets are molecules that show stable magnetisation of purely molecular origin, due to their magnetic anisotropy. They are promising candidates for a bottom-up approach to magnetic data storage materials. One of the advantages is that all the molecules are the same and there is no distribution in the size of the particles. However, the blocking temperature of the magnetisation is still too low. Here we propose to study three classes of single molecule magnets that may show higher blocking temperatures: First of all, those composed of high-anisotropy ions, secondly, those containing ions with an orbital moment, and finally those containing lanthanide ions. We will study these systems using a combination of magnetometry and frequency domain magnetic resonance spectroscopy. The latter is a method that is new to the UK.

该提案旨在确定制备更好的单分子磁体的新策略。单分子磁体是由于其磁各向异性而表现出纯分子起源的稳定磁化强度的分子。它们是磁性数据存储材料自下而上方法的有希望的候选者。优点之一是所有分子都是相同的，并且颗粒大小没有分布。然而，磁化的截止温度仍然太低。在这里，我们建议研究三类可能表现出更高阻挡温度的单分子磁体：首先是由高各向异性离子组成的磁体，其次是含有轨道矩离子的磁体，最后是含有镧系离子的磁体。我们将结合磁力测量和频域磁共振波谱来研究这些系统。后者对英国来说是一种新方法。
