The magnetic properties of single atoms are significantly affected by details in the atomic- scale surrounding. One strategy to control the spin state and magnetic anisotropy is to embed the atoms into specifically designed organic ligands. Moreover, the surface plays a pivotal role in the magnetic properties when it interacts with the magnetic core. Here, we utilize scanning tunneling microscopy and spectroscopy to characterize the magnetic anisotropy and lifetimes of excited states of single paramagnetic molecules on a surface and point out possibilities to tune these.
