Single-Molecule Magnets (SMMs) and Single-Ion Magnets (SIMs)

单分子磁体（SMMs）和单离子磁体（SIMs）是结合了块状磁体的宏观特性和分子的量子力学特性的分子。我们在这个项目中的目标是i)通过配体设计控制晶体场来调整镧系SIMs[1-5]的磁性能，ii)测试它们在作为薄膜沉积时与不同表面衬底的相互作用。镧系SIMs及其薄膜的磁性将在格拉斯哥（SIMs）和利兹（films）进行测量。镧系SIMs的最大挑战是抑制通过磁化（QTM）和自旋声子（拉曼）弛豫过程的量子隧穿而产生的不必要的磁弛豫。因此，我们项目的最终目标是利用晶体场设计和/或分子/表面界面来改变自旋声子相互作用，从而提高这些磁性分子的阻断温度。

Single-Molecule Magnets (SMMs) and Single-Ion Magnets (SIMs) are molecules that combine the macroscopic properties of bulk magnets with the quantum mechanical properties of molecules. Our aim in this project is to i) tune the magnetic properties of lanthanide SIMs [1-5] by controlling the crystal field through ligand design and ii) test their interaction with different surface substrates when deposited as thin films. The resulting magnetic properties of the lanthanide SIMs and their films will be measured in Glasgow (SIMs) and Leeds (films). The big challenge in lanthanide SIMs is to suppress the unwanted magnetic relaxation that occurs via quantum tunnelling of the magnetisation (QTM) and spin-phonon (Raman) relaxation processes. Hence, the ultimate aim of our project is to use the crystal field design and/or molecule/surface interface to modify the spin-phonon interaction and hence to improve the blocking temperature of these magnetic molecules.
