Elemental topological ferroelectrics and polar metals of few-layer materials
Hu Zhang, Lulu Zhao, RuiFeng Zhang +6
Ferroelectricity can exist in elemental phases as a result of charge transfers between atoms occupying inequivalent Wyckoff positions. We investigate the emergence of ferroelectric…
Copper-based charge transfer multiferroics with a configuration
Hu Zhang, RuiFeng Zhang, Lulu Zhao +6
Multiferroics are materials with a coexistence of magnetic and ferroelectric order allowing the manipulation of magnetism by applications of an electric field through magnetoelectr…
From a superconductor NdNiO to a Mott multiferroic BiNiO
Hu Zhang, RuiFeng Zhang, Lulu Zhao +6
Motivated by the recently discovered superconductivity in Sr-doped nickelate oxides NdNiO, we predict a material BiNiO that provides an opportunity to study the intertwined…
Spin field-effect transistors based on massless birefringent Dirac fermions in polar Dirac semimetals
Hu Zhang, Chendong Jin, Ruqian Lian +4
The Datta-Das-type spin field-effect transistor, using a two-dimensional electron gas in a semiconductor heterostructure as a channel, plays a key role in spintronics. Here, we the…
Double version of the Rashba and Dresselhaus spin-orbit coupling
Hu Zhang, Lulu Zhao, Chendong Jin +5
The Rashba and Dresselhaus types of spin-orbit coupling are two typical linear coupling forms. We establish the fundamental physics of a model which can be viewed as the double ver…
Interaction between defect and skyrmion in nanodisk
Chengkun Song, Chendong Jin, Haiyan Xia +4
Magnetic skyrmions are topologically protected stable magnetization configurations, which are expected to be a promising candidate as information carrier, while defect is inevitabl…
Spin current pumped by resonant skyrmion
Chunlei Zhang, Jianing Wang, Chendong Jin +3
Spin pumping is a widely recognized method to generate the spin current in the spintronics, which is acknowledged as a fundamentally dynamic process equivalent to the spin-transfer…
Dynamics of a magnetic skyrmionium in an anisotropy gradient
Chengkun Song, Chendong Jin, Yunxu Ma +4
Magnetic skyrmionium is a novel magnetization configuration with zero skyrmion number, which is composed by two skyrmions with opposite skyrmion number. Here, we study the dynamics…
Field-tuned spin excitation spectrum of -skyrmion
Chengkun Song, Yunxu Ma, Chendong Jin +4
We study spin-wave excitation modes of skyrmion in a magnetic nanodot under an external magnetic field along -direction using micromagnetic simulations based on Landau-Lifs…
Current-induced motion of twisted skyrmions
Chendong Jin, Chunlei Zhang, Chengkun Song +7
Twisted skyrmions, whose helicity angles are different from that of Bloch skyrmions and Néel skyrmions, have already been demonstrated in experiments recently. In this work, we fir…
Directional Spin-wave Propagation in the Skyrmion Chain
Chunlei Zhang, Chendong Jin, Jinshuai Wang +4
The Dzyaloshinskii-Moriya interaction (DMI), favoring a chiral spin structure like the skyrmion, gives rise to the nonreciprocal propagation of spin waves. We investigate the propa…
Magnetic field direction dependent antiskyrmion motion with microwave electric fields
Chengkun Song, Chendong Jin, Haiyan Xia +4
Magnetic skyrmions are regarded as promising information candidates in future spintronic devices, which have been investigated theoretically and experimentally in isotropic system.…
