Quantum effects in molecular single-ion magnets

AbstractCrystals of single-molecule magnets provide unique opportunities for the investigation of quantum magnetism. Generally, these systems are formed by clusters made of a polynuclear magnetic core. However, it has been recently shown that molecules encapsulating an individual magnetic ion can also exhibit SMM behavior. In these systems, known as single-ion magnets, the quantum effects are much more pronounced than in the more complex cluster-type SMMs. In this paper we will show that the spin dynamics, and in particular the quantum tunneling effects of these systems, can be controlled by chemical design (symmetry control of the magnetic site, magnetic dilution of the crystals,…). On the other hand, we will show that these molecules can be potential candidates to act as spin qubits as they possess a well defined ground state doublet with a high quantum coherence.
