The vector-spin-chirality bound state driven by the inverse Dzyaloshinskii-Moriya mechanism can be coupled with phonons and has richer physical phenomena. A one-dimensional antiferromagnetic chain with spin chirality-phonons coupling model is studied in the conditions ...
综上所述,我们系统地证明了垂直合成反铁磁结构中的确定性无场磁化开关,其中Dzyaloshinskii-Moriya相互作用的定制强度在配置畴壁中起主要作用,提高了自旋轨道转矩效率。当畴壁能量有效场与DMI有效场相当时,畴壁呈现出介于Bloch型和Néel型之间的结构,易于被外界场控制。通过在楔形SOC层上沉积[Co/Pd]/Ru/[Co/Pd]/Ru...
We have derived an expression of the Dzyaloshinskii-Moriya (DM) interaction, where all the three components of the DM vector can be calculated independently, for a general, non-collinear magnetic configuration. The formalism is implemented in a real space - linear muffin-tin orbital - atomic ...
\(\:\varvec{D}\) represents the Dzyaloshinskii -Moriya vector for the left electrode. All of these parameters are unitless quantities. For the simulation model setup, the \(\:{J}_{l}\) and \(\:{J}_{R}\) were fixed at 1 to ensure both electrodes were ferromagnetic. The molecule-...
采用Negativity理论研究了具有Dzyaloshinskii—Moriya(DM)相互作用的伊辛模型在非均匀磁场 中的纠缠特性。结果发现,DM相互作用的存在明显增强了两量子比特间的热纠缠并且能够把纠缠增加到一个 最大值0.5;而外磁场具有减小热纠缠的作用。温度的高低也直接影响热纠缠。另外,讨论了磁场的非均匀性对 伊辛链热纠缠的影响,在一...
Following the Moriya symmetry rules67, the DMI vector is in the form of dij = dðz^ × u^ijÞ, where d is the microscopic DMI constant, and z^ and u^ij are unit vectors pointing normal to the interface and from site i to j, respectively. Because the reflection symmetry of the...
However, it is limited to linear spinwave modes. The Dzyaloshinskii–Moriya interaction is shown to modify the spin wave spectrum of the bilayers, making its low energy part qualitatively similar to the electronic spectrum of the Rashba spin–orbit model....
Introduction The Dzyaloshinskii–Moriya interaction (DMI) has attracted much attention because of its peculiar properties for realizing chiral spin structures in magnetic systems with broken inversion symmetry1–10. These chiral spin structures, such as chiral magnetic domain walls1 and magnetic skyrmions2...
Polarized neutron scatteringQuantized spin modelsDzyaloshinskii–Moriya (DM) interaction in the paramagnetic state leads to the incommensurate spin fluctuations with incommensurate vector proportional to the relative strength of the DM interaction. We show that the DM interaction leads to helical spin ...
Dzyaloshinskii–Moriya interactionWe investigate the effects of the directions of Dzyaloshinskii—Moriya (DM) interaction vector and magnetic field on the quantum discord in the pure DM model. For different directions of DM vector, we find that there are different optimal parameter components of ...
