In Physics, antisymmetric exchange, also known as the Dzyaloshinskii–Moriya interaction (DMI), is a contribution to the total magnetic exchange interaction between two neighboring magnetic spins, $${\displaystyle \mathbf {S} _{i}}$$ and $${\displaystyle \mathbf {S} _{j}}$$. … See more The discovery of antisymmetric exchange originated in the early 20th century from the controversial observation of weak ferromagnetism in typically antiferromagnetic α-Fe2O3 crystals. In 1958, See more The Dzyaloshinskii–Moriya interaction has proven difficult to experimentally measure directly due to its typically weak effects and similarity to other magnetoelectric effects in bulk materials. Attempts to quantify the DMI vector have utilized X-ray diffraction See more Magnetic skyrmions A magnetic skyrmion is a magnetic texture that occurs in the magnetization field. They exist in spiral or hedgehog configurations that … See more The functional form of the DMI can be obtained through a second-order perturbative analysis of the spin-orbit coupling interaction, See more The image at right displays a coordinated heavy metal-oxide complex that can display ferromagnetic or antiferromagnetic behavior depending … See more • Exchange interaction • Spin–orbit coupling • Superexchange • Landau theory • Skyrmions • Multiferroics See more WebAug 13, 2024 · Dzyaloshinskii–Moriya interaction (DMI) is considered as one of the most important energies for specific chiral textures such as magnetic skyrmions.
