Strategies towards single molecule magnets based on lanthanide ions
Roberta Sessoli,Annie K. Powell +1 more
TL;DR: In this article, the authors reviewed the synthetic strategies employed in a concerted effort to obtain new single molecule magnets based on lanthanide ions in the framework of the research program on Molecular Magnetism funded by the Deutsche Forschungsgemeinschaft.
Journal ArticleDOI
Dysprosium triangles showing single-molecule magnet behavior of thermally excited spin states
Jinkui Tang,Ian J. Hewitt,N. T. Madhu,Guillaume Chastanet,Wolfgang Wernsdorfer,Christopher E. Anson,Crifstiano Benelli,Roberta Sessoli,Annie K. Powell +8 more
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.
Journal ArticleDOI
Strong axiality and Ising exchange interaction suppress zero-field tunneling of magnetization of an asymmetric Dy2 single-molecule magnet.
Yun-Nan Guo,Gong-Feng Xu,Wolfgang Wernsdorfer,Liviu Ungur,Yang Guo,Jinkui Tang,Hongjie Zhang,Liviu F. Chibotaru,Annie K. Powell +8 more
TL;DR: The high axiality and Ising exchange interaction efficiently suppress quantum tunneling of magnetization of an asymmetric dinuclear Dy(III) complex, as revealed by combined experimental and theoretical investigations.
