Achieving outstanding heat-resistant properties in Mg alloy via constructing stable solute-network

Materials Research Letters, 2023
A new Mg–Sm–Ce–Mn-based alloying system with a large miscibility gap was uncovered, and multi-solute co-segregations at high-angular grain boundaries (HAGBs), dislocations and low-angular grain boundaries (LAGBs) are obtained after the proper extrusion ...

Macrospin approximation and quantum effects in models for magnetization reversal

, 2011
The thermal activation of magnetization reversal in magnetic nanoparticles is controlled by the anisotropy-energy barrier. Using perturbation theory, exact diagonalization and stability analysis of the ferromagnetic spin-s Heisenberg model with coupling ...

(INVITED)Laser-driven white light with tunable low-colour temperature based on novel ZrO2-doped (Gd,Lu)2O3:Eu red-emitting transparent ceramics

Optical Materials: X, 2022
Novel red-emitting ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics were fabricated via a vacuum sintering method. The f–f transitions of Eu3+ in the ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics have much higher intensity than the ...

Phenomenological description of anisotropy effects in some ferromagnetic superconductors

, 2014
We study phenomenologically by using the previously derived Landau free energy, the role of anisotropy in ferromagnetic superconductors UGe2, URhGe, and UCoGe. The three compounds are separately discussed with the special stress on UGe2.

In situ coupling of NiFe nanoparticles on carbonized wood for oxygen evolution reaction

Catalysis Communications, 2022
Inspired by the 3D hierarchical porous structure and abundant hydroxyl groups of wood, we used basswood as a biological template to synthesize NiFe/porous carbon (C) through an impregnation and pyrolysis strategy. The optimized NiFe/C composite exhibited

Macrospin limit and configurational anisotropy in nanoscale Permalloy triangles

, 2009
In Permalloy submicron triangles, configurational anisotropy - a higher-order form of shape anisotropy - yields three equivalent easy axes, imposed by the structures' symmetry order.

Defect related switching field reduction in small magnetic particle arrays [PDF]

, 2003
An array of 42 mum square, 3 mum thick garnet particles has been studied. The strong crystalline uniaxial anisotropy of these particles results in the stable remanent state being single domain with magnetization parallel to the film normal. Magneto-optic
