Low Field Magnetic and Thermal Hysteresis in Antiferromagnetic Dysprosium

open access: yesMetals, 2017
Magnetic and thermal hysteresis (difference in magnetic properties on cooling and heating) have been studied in polycrystalline Dy (dysprosium) between 80 and 250 K using measurements of the reversible Villari effect and alternating current (AC ...

Current effect on magnetization oscillations in a ferromagnet - antiferromagnet junction [PDF]

open access: yesarXiv, 2011
Spin-polarized current effect is studied on the static and dynamic magnetization of the antiferromagnet in a ferromagnet - antiferromagnet junction. The macrospin approximation is generalized to antiferromagnets. Canted antiferromagnetic configuration and resulting magnetic moment are induced by an external magnetic field.

THE ANTIFERROMAGNETIC POTTS MODEL

open access: yesModern Physics Letters B, 2011
We review the exact results on the various critical regimes of the antiferromagnetic Q-state Potts model. We focus on the Bethe Ansatz approach for generic Q, and describe in each case the effective degrees of freedom appearing in the continuum limit.

Self‐Assembly Engineering of Fullerene‐Like Polyhedra: V60, V66, V72 From {MV5} Pentagonal Second Building Block

open access: yesAdvanced Science, EarlyView.
A precise self‐assembly of fullerene‐like V60‐MOP constructed from the first discovered polyoxovanadates five‐membered ring V5 units is discovered. In situ modifications are successfully used to insert {MO5} (M = V/Mo) in the center of the V5 ring, resulting in three other isomorphic spherical cages V66‐MOP, V72‐MOP, and V60Mo12‐MOP.

Serrated Leaf‐Like N‐Doped Copper Sulfide Enabling Bifunctional Oxygen Reduction/Evolution via Dual‐Mode Cathode Reactions for High Energy Density and Cycle Stability in Zinc–Air Batteries

open access: yesAdvanced Science, EarlyView.
A serrated leaf‐like nitrogen‐doped copper sulfide (N‐CuS) cathode with hybridized N 2p – S 3p orbitals is presented, mesopores for oxygen transport, and a five times larger electrochemical active surface area than Cu. In aerobic conditions, a zinc–air battery with N‐CuS achieves 788 mAh g⁻¹ and 916 Wh kg⁻¹, outperforming Pt/C+RuO₂.

Synthetic Antiferromagnetic Spintronics: Part of a collection of reviews on antiferromagnetic spintronics [PDF]

open access: yesarXiv, 2017
Spintronic and nanomagnetic devices often derive their functionality from layers of different materials and the interfaces between them. This is especially true for synthetic antiferromagnets - two or more ferromagnetic layers that are separated by metallic spacers or tunnel barriers and which have antiparallel magnetizations.
