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.

单分子磁体(SMM)和单离子磁体(SIMS)是结合了块体磁体的宏观性质和分子的量子力学性质的分子。我们在这个项目中的目的是：1)通过配位设计控制晶场来调节稀土元素SIMS[1-5]的磁性；2)测试它们在沉积成薄膜时与不同表面衬底的相互作用。将在格拉斯哥(SIMS)和利兹(薄膜)测量镧系元素SIMS及其薄膜的最终磁性。镧系元素SIMS的最大挑战是抑制通过磁化(QTM)和自旋-声子(拉曼)弛豫过程的量子隧道而发生的不必要的磁弛豫。因此，我们项目的最终目的是利用晶场设计和/或分子/表面界面来修饰自旋-声子相互作用，从而提高这些磁性分子的阻塞温度。
