Abstract

Lanthanide compounds show much higher energy barriers to magnetic relaxation than
3d-block compounds, and this has led to speculation that they could be used in molecular
spintronic devices. Prototype molecular spin valves and molecular transistors have been
reported, with remarkable experiments showing the influence of nuclear hyperfine coupling
on transport properties. Modelling magnetic data measured on lanthanides is always com
plicated due to the strong spin–orbit coupling and subtle crystal field effects observed for the
4f-ions; this problem becomes still more challenging when interactions between lanthanide
ions are also important. Such interactions have been shown to hinder and enhance magnetic
relaxation in different examples, hence understanding their nature is vital. Here we are able to
measure directly the interaction between two dysprosium(III) ions through multi-frequency
electron paramagnetic resonance spectroscopy and other techniques, and explain how this
influences the dynamic magnetic behaviour of the system
