“…This minor loop field segment, when extended from H r to −H s , constitutes a FORC [20,29]. This correspondence motivates the use of FORC magnetometry to understand the observed hysteretic stability of skyrmions at ZF [36][37][38][39]. Fig.…”

Competing interactions produce finite-sized textures in myriad condensed matter systems -typically forming elongated "stripe" or round "bubble" domains. Transitions between stripe and bubble phases, driven by field or temperature, are expected to be reversible in nature. Here we report on the distinct character of the analogous transition for nanoscale spin textures in chiral Co/Pt-based multilayer films -known to host Néel skyrmions -using microscopy, magnetometry, and micromagnetic simulations. Upon increasing field, individual stripes fission into multiple skyrmions, and this transition exhibits a macroscopic signature of irreversibility. Crucially, upon field reversal, the skyrmions do not fuse back into stripes -with many skyrmions retaining their morphology down to zero field. Both the macroscopic irreversibility and the microscopic zero field skyrmion density are governed by the thermodynamic material parameter determining chiral domain stability. These results establish the thermodynamic and microscopic framework underlying ambient skyrmion generation and stability in chiral multilayer films and provide immediate directions for their functionalization in devices.

“…Another important consequence of relativistic effects i.e., SOC combined with a broken spatial inversion symmetry, is the appearance of Dzyaloshinskii-Moriya interaction (DMI) [33,34]. DMI, characterized by a Dzyaloshinskii-Moriya vector D acting on a pair of spins, is an antisymmetric magnetic exchange interaction that aligns the neighbouring spins orthogonally to each other, with a unique sense of rotation, instead of the parallel or antiparallel spin alignments obtained by the usual Heisenberg exchange interaction [35]. DMI is essential for creating non-collinear long-range spin order in ultra-thin magnetic films, and is responsible in the creation, stabilisation and manipulation of skyrmions and chiral domain walls as bearers of attractive applications in novel spintronic, memory and logic devices [36,37].…”

Using relativistic density-functional calculations, we examine the magneto-crystalline anisotropy and exchange properties of transition-metal atoms adsorbed on 2D-GaAs. We show that single Mn and Mo atom (Co and Os) strongly bind on 2D-GaAs, and induce local out-of-plane (in-plane) magnetic anisotropy. When a pair of TM atoms is adsorbed on 2D-GaAs in a close range from each other, magnetisation properties change (become tunable) with respect to concentrations and ordering of the adatoms. In all cases, we reveal presence of strong Dzyaloshinskii–Moriya interaction. These results indicate novel pathways towards two-dimensional chiral magnetic materials by design, tailored for desired applications in magneto-electronics.
