Journal ArticleDOI
Magnetic relaxation pathways in lanthanide single-molecule magnets
Robin J. Blagg,Liviu Ungur,Floriana Tuna,James Speak,Priyanka Comar,David Collison,Wolfgang Wernsdorfer,Eric J. L. McInnes,Liviu F. Chibotaru,Richard E. P. Winpenny +9 more
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.
Journal ArticleDOI
Single Pyramid Magnets: Dy5 Pyramids with Slow Magnetic Relaxation to 40 K
TL;DR: 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.
Journal ArticleDOI
Engineering the coupling between molecular spin qubits by coordination chemistry
Grigore A. Timco,Stefano Carretta,Filippo Troiani,Floriana Tuna,Robin J. Pritchard,Christopher A. Muryn,Eric J. L. McInnes,Alberto Ghirri,Andrea Candini,Paolo Santini,Giuseppe Amoretti,Marco Affronte,Richard E. P. Winpenny +12 more
TL;DR: Antiferromagnetic Cr7Ni rings can be chemically linked to each other and that the coupling between their spins can be tuned by choosing the linker, and calculations are presented that demonstrate how realistic microwave pulse sequences could be used to generate maximally entangled states in such molecules.
Journal ArticleDOI
Co-Ln mixed-metal phosphonate grids and cages as molecular magnetic refrigerants
TL;DR: The synthesis, structures, and magnetic properties of six families of cobalt-lanthanide mixed-metal phosphonate complexes are reported, and the maximum magnetocaloric effect (MCE) has been observed for the Ln = Gd derivative, with a smaller MCE for the compounds containing magnetically anisotropic 4f-ions.
Journal ArticleDOI
Limits on Intrinsic Magnetism in Graphene
M. Sepioni,Rahul R. Nair,S. Rablen,J. Narayanan,Floriana Tuna,Richard E. P. Winpenny,A. K. Geim,Irina V. Grigorieva +7 more
TL;DR: Graphene nanocrystals obtained by sonic exfoliation of graphite are studied, yielding a single species of defects responsible for the paramagnetism, with approximately one magnetic moment per typical graphene crystallite.
