The dominant mechanisms of magnetization relaxation in the bulk phase are discussed followed by an overview of SIMs relevant for surface deposition and the recent experiments on surface-deposited SIMs will be reviewed, along with a discussion of future perspectives.
Symmetry strategies for high performance lanthanide-based single-molecule magnets.
In this review, crystal-field theory is employed to demonstrate the electronic structures according to the semiquantitative electrostatic model and specific symmetry elements are analysed for the elimination of transverse crystal fields and quantum tunnelling of magnetization (QTM).
