Metal–Metal-Bonded Fe₄ Clusters with Slow Magnetic Relaxation

Inorganic Chemistry, 2022
Reaction of FeBr2 with Li(N═CtBu2) (0.5 equiv) and Zn0 (2 equiv) results in the formation of the formally mixed-valent cluster [Fe4Br2(N═CtBu2)4] (1) in moderate yield. The subsequent reaction of 1 with Na(N═CtBu2) results in formation of [Fe4Br(N═CtBu2)5] (2), also in moderate yield.

Synchrotron radiation by fast fermions in heavy-ion collisions [PDF]

, 2010
We study the synchrotron radiation of gluons by fast quarks in strong magnetic field produced by colliding relativistic heavy-ions. We argue that due to high electric conductivity of plasma, time variation of the magnetic field is slow and estimate its ...

Divalent Thulium Crown Ether Complexes with Field-Induced Slow Magnetic Relaxation.

Inorganic Chemistry, 2019
The tailoring of the coordination chemistry around f-element centers is a crucial step for the development of compounds with slow magnetic relaxation, including single-molecule magnets (SMMs), which have great potential in molecular spintronics and for ...

Magnetic relaxation in finite two-dimensional nanoparticle ensembles

, 2003
We study the slow phase of thermally activated magnetic relaxation in finite two-dimensional ensembles of dipolar interacting ferromagnetic nanoparticles whose easy axes of magnetization are perpendicular to the distribution plane. We develop a method to

Pushing the limits of magnetic anisotropy in trigonal bipyramidal Ni(II) [PDF]

, 2015
Monometallic complexes based on 3d transition metal ions in certain axial coordination environments can exhibit appreciably enhanced magnetic anisotropy, important for memory applications, due to stabilisation of an unquenched orbital moment.

Slow Magnetic Relaxation Triggered by a Structural Phase Transition in Long-Chain-Alkylated Cobalt(II) Single-Ion Magnets.

Inorganic Chemistry, 2019
The behavior of single-ion magnets (SIMs) that reflects large distortions of their coordination environments caused by the packing of long alkyl chains for two Co(II) complexes of the type [Co(C n-terpy)2](BF4)2 (C n-terpy = 4'-alkoxy-2,2':6',2 ...
