TLDR
The thermal energy barrier to relaxation of magnetization of this single-molecule magnet was found at a temperature of 530 K and is the largest yet observed for any d- or f-block cluster compound.Abstract:
Single-molecule magnets: A square-pyramidal pentametallic dysprosium cluster was synthesized and showed slow magnetic relaxation at temperatures as high as 40 K. The thermal energy barrier to relaxation of magnetization of this single-molecule magnet was found at a temperature of 530 K and is the largest yet observed for any d- or f-block cluster compound.read more

Recent advances in dysprosium-based single molecule magnets: Structural overview and synthetic strategies
TL;DR: In this paper, the authors demonstrate the research developed in the few years in the fascinating and challenging field of Dy-based SMMs with particular focus on how recent studies tend to address the issue of relaxation dynamics in these systems from synthetic point of view.

Symmetry strategies for high performance lanthanide-based single-molecule magnets
TL;DR: 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).

TL;DR: Polylanthanide alkoxide cage complexes, and their doped diamagnetic yttrium analogues, are reported, in which competing relaxation pathways are observed and relaxation through the first excited state can be quenched, leading to energy barriers for relaxation of magnetization that exceed 800 K.

Lanthanide Double-Decker Complexes Functioning as Magnets at the Single-Molecular Level
TL;DR: Double-decker phthalocyanine complexes with Tb3+ or Dy3+ showed slow magnetization relaxation as a single-molecular property and a significant temperature rise results from a mechanism in the relaxation process different from that in the transition-metal-cluster SMMs.

TL;DR: This single lanthanide ion polyoxometalate is the inorganic analogue of the bis(phthalocyaninato)lanthanide SMMs, both exhibiting very similar ligand field symmetries around the lanthanides ion (idealized D4d).

TL;DR: In the lanthanide-containing phthalocyanine complexes reported in the literature the ligand environment induces a large splitting of the ground Jmanifold, whereas in SMMs large-spin ground states arising from magnetic interactions between the metal centers of the cluster can enhance the weaker single-ion.

TL;DR: Structural distortion in a [Mn6] complex switches the magnetic exchange from antiferro- to ferromagnetic, resulting in a single-molecule magnet with a record anisotropy barrier.
