Antiferromagnetic domain wall as spin wave polarizer and retarder [PDF]

Nature Communications, 2017
As a collective quasiparticle excitation of the magnetic order in magnetic materials, spin wave, or magnon when quantized, can propagate in both conducting and insulating materials.

Hybrid functional study on the ferroelectricity of domain walls with O-vacancies in PbTiO3

Mechanical Engineering Journal, 2015
Nonlinear defect interactions between the 180° domain wall and oxygen-vacancies (O-vacancies) in PbTiO3, and the characteristic ferroelectricity due to the interactions are investigated using first-principles calculations based on the hybrid Hartree-Fock

Fast domain wall motion in the vicinity of the angular momentum compensation temperature of ferrimagnets. [PDF]

Nature Materials, 2017
Antiferromagnetic spintronics is an emerging research field which aims to utilize antiferromagnets as core elements in spintronic devices. A central motivation towards this direction is that antiferromagnetic spin dynamics is expected to be much faster ...

Vector-field domain walls [PDF]

Physical Review D, 2009
We argue that spontaneous Lorentz violation may generally lead to metastable domain walls related to the simultaneous violation of some accompanying discrete symmetries. Remarkably, such domain wall solutions exist for space-like Lorentz violation and do not exist for the time-like violation. Because a preferred space direction is spontaneously induced,

Dynamics of hard rods with initial domain wall state [PDF]

, 2017
Inspired by recent results on the non-equilibrium dynamics of many-body quantum systems, we study the classical hard rod problem in one dimension with initial domain wall condition.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Skyrmion Pair Racetrack Utilizing Hall Motion

Magnetochemistry
The skyrmion racetrack is a promising concept for future information technology. The primary issues with skyrmion racetrack memory are now error codes and Hall motion. Here, we propose a skyrmion pair racetrack memory. The Oersted fields generated by the

General nature of the step-induced frustration at ferromagnetic/antiferromagnetic interfaces: topological origin and quantitative understanding

New Journal of Physics, 2019
We present a study of the magnetic configuration due to step-induced magnetic frustration at ferromagnetic/antiferromagnetic (FM/AFM) interfaces. At a substrate monatomic step edge, a 180° domain wall emerges.

Domain Wall Architecture in Tetragonal Ferroelectric Thin Films [PDF]

Advances in Materials, 2017
Non-Ising-like 180° ferroelectric domain wall architecture and domain distribution in tetragonal PbZrx Ti1-x O3 thin films are probed using a combination of optical second harmonic generation and scanning transmission electron microscopy.
