First-principles calculations for Dzyaloshinskii–Moriya interaction

Spin-Chirality-Driven Quantum Anomalous and Quantum Topological Hall Effects in Chiral Magnets

“…The vector-spin structures for kagome chiral magnets can be controlled experimentally via rotating the in-plane spins by means of magnetic, electrical, strain, or temperature effects . Moreover, the scalar-spin cases can be also realized via canting the spins along the out-of-plane direction by applying an external magnetic field, a hydrostatic pressure, or thermal fluctuations in the presence of Dzyaloshinskii–Moriya interactions . Thus, our findings are a crucial step to realize antiferromagnetic quantum spintronics integrating the properties of the QAHE and AFMs. − …”

Strain-tunable skyrmions in two-dimensional monolayer Janus magnets

“…The intrinsically broken inversion symmetry, together with the feasibility of tunable electronic properties by a selection of a suitable pair of chalcogen elements in Janus ML-TMD, inspired us to speculate that a large DMI can be obtained in 2D magnetic Janus materials. In addition, by studying CrXTe 36 and MnSeTe 37 monolayers, Yang et al 38 found that biaxial strain could effectively manipulate the magnetic parameters of Janus MLs. With this conjecture, we investigate the structural and magnetic behavior of a series of Janus MLs of dichalcogenides XSeTe (X = Nb, Re) via first-principles calculations.…”

Correlation of Interface Interdiffusion and Skyrmionic Phases

“…Interface-induced effects on physical properties arising in ferromagnetic/heavy-metal (FM/HM) heterostructures have been explored as a platform to host a plethora of novel two-dimensional topological magnetic structures such as, skyrmions, − skyrmioniums, − and bimerons. , These chiral magnetic textures are primarily induced by the Dzyaloshinskii-Moriya interaction (DMI), ,− which arises in these magnetic systems with intrinsic broken inversion symmetry, combined with strong spin–orbit interaction (SOI) provided by the heavy atoms at FM/HM interfaces. − …”
