Symmetry demanded topological nodal-line materials

open access: yesAdvances in Physics: X, 2018
The realization of Dirac and Weyl physics in solids has made topological materials one of the main focuses of condensed matter physics. Recently, the topic of topological nodal line semimetals, materials in which Dirac or Weyl-like crossings along ...

SiAlON Microstructures

open access: yesJournal of the Ceramic Society of Japan, 2008
This paper is focussed on the development of microstructure during liquid phase sintering and post-densification crystallisation heat treatment of ceramic materials based on the α- and β-Si3N4 structures. Grain shape and size distributions, assessed by quantitative microscopy in combination with stereological methods, and fine scale microstructures ...

Elliptical Bloch skyrmion chiral twins in an antiskyrmion system

open access: yesNature Communications, 2020
Skyrmions and anti-skyrmions often exist in distinct material systems. Here, the authors observe elliptical skyrmions and anti-skyrmions with opposite topological charges in one tetragonal Heusler compound Mn1.4Pt0.9Pd0.1Sn with D 2d symmetry.

Recrystallization microstructure modelling from superimposed deformed microstructure on microstructure model

open access: yesBulletin of Materials Science, 2009
The recovered cold rolled microstructure obtained from orientation image microstructure of Al-4%Mg-0·5%Mn alloy (AA5182 alloy) was superimposed on the grid of cellular automata based microstructure model. The Taylor factors of deformed/cold rolled orientations were considered as the driving force for recrystallization.

Accelerated Progression of Gait Impairment in Parkinson's Disease and REM Sleep Without Atonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with Parkinson's disease (PD) and rapid eye movement (REM) sleep without atonia (RSWA) often have more severe gait disturbances compared to PD without RSWA. The association between the presence and expression of RSWA and the rate of progression of gait impairment in PD is unknown.

Highly efficient current-induced domain wall motion in a room temperature van der Waals magnet

open access: yesNature Communications
Two-dimensional van der Waals magnets are highly promising for next-generation spintronics. The ferromagnetic material Fe3GaTe2 is especially interesting due to its high Curie temperature.
