Zero-Field Slow Magnetic Relaxation and Hysteresis Loop in Four-Coordinate CoII Single-Ion Magnets with Strong Easy-Axis Anisotropy.

Inorganic Chemistry, 2019
Two mononuclear tetrahedral Co(II) complexes (HNEt3)2[Co(L1)2]·H2O (1) and (Bu4N)2[Co(L2)2]·H2O (2) (H2L1 = N,N'-bis(p-toluenesulfony1)oxamide, H2L2 = N,N'-diphenyloxamide) have been synthesized, and their structures have been characterized by single ...

Levamisole Based Co(II) Single‐Ion Magnet

Chemistry – An Asian Journal
AbstractA new Co(II) complex, [Co(NCS)2(L)2] (1) has been synthesized based on levamisole (L) as a new ligand. Single‐crystal X‐ray diffraction analyses confirm that the Co(II) ion is having a distorted tetrahedral coordination geometry in the complex.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Prospects for observing the magnetorotational instability in the Plasma Couette Experiment

, 2015
Many astrophysical disks, such as protoplanetary disks, are in a regime where non-ideal, plasma-specific magnetohydrodynamic (MHD) effects can significantly influence the behavior of the magnetorotational instability (MRI).

Multiscale examination of strain effects in Nd-Fe-B permanent magnets

, 2017
We have performed a combined first-principles and micromagnetic study on the strain effects in Nd-Fe-B magnets. First-principles calculations on Nd2Fe14B reveal that the magnetocrystalline anisotropy (K) is insensitive to the deformation along c axis and

Bubble and Skyrmion Crystals in Frustrated Magnets with Easy-Axis Anisotropy [PDF]

, 2016
We clarify the conditions for the emergence of multiple-${\bf Q}$ structures out of lattice and easy-axis spin anisotropy in frustrated magnets. By considering magnets whose exchange interaction has multiple global minima in momentum space, we find that ...

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 ...

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

Advanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
