Journal ArticleDOI
Molecular magnetic hysteresis at 60 kelvin in dysprosocenium.
TL;DR: Ab initio calculations of spin dynamics demonstrate that magnetic relaxation at high temperatures is due to local molecular vibrations, indicating that magnetic data storage in single molecules at temperatures above liquid nitrogen should be possible.
Journal ArticleDOI
Field- and temperature-dependent quantum tunnelling of the magnetisation in a large barrier single-molecule magnet
You-Song Ding,Ke-Xin Yu,Daniel Reta,Fabrizio Ortu,Richard E. P. Winpenny,Yan-Zhen Zheng,Nicholas F. Chilton +6 more
TL;DR: The authors conduct a field- and temperature-dependent study of the magnetisation dynamics of a dysprosium-based SMM, finding four distinct relaxation processes that dominate in different regimes.
Journal ArticleDOI
Synthesis and Electronic Structures of Heavy Lanthanide Metallocenium Cations
TL;DR: It is proposed that the exclusive presence of multihapto ligands in 1-Dy is the origin of its remarkable magnetic properties and appears vital for realizing the next generation of high-temperature single-molecule magnets.
Journal ArticleDOI
Actinide covalency measured by pulsed electron paramagnetic resonance spectroscopy
Alasdair Formanuik,Ana-Maria Ariciu,Fabrizio Ortu,Reece Beekmeyer,Andrew Kerridge,Floriana Tuna,Eric J. L. McInnes,David P. Mills +7 more
TL;DR: The hyperfine sublevel correlation technique is applied to quantify the electron-spin density at ligand nuclei in molecular thorium( III) and uranium(III) species and therefore the extent of covalency and will be important in developing the understanding of the chemical bonding, andTherefore the reactivity, of actinides.
Journal ArticleDOI
Understanding magnetic relaxation in single-ion magnets with high blocking temperature
Alessandro Chiesa,F. Cugini,Riaz Hussain,Riaz Hussain,E. Macaluso,Giuseppe Allodi,E. Garlatti,Marcus J. Giansiracusa,Conrad A. P. Goodwin,Fabrizio Ortu,Daniel Reta,Jonathan M. Skelton,Tatiana Guidi,Paolo Santini,Massimo Solzi,R. De Renzi,David P. Mills,Nicholas F. Chilton,Stefano Carretta +18 more
TL;DR: In this article, the authors derive a general recipe to design high-blocking-temperature rare-earth single-ion magnets with magnetic hysteresis above liquid-nitrogen temperatures.
