The study aims to investigate the coexistence of skyrmions and anti-skyrmions in the NiI2 monolayer influenced by specific interactions and strain.
Analyzed the spin spiral state in monolayer NiI2.
Evaluated the effects of biaxial strain on skyrmion dynamics.
Investigated higher-order interactions and their impact on stability.
Identified a field-free state where skyrmions and anti-skyrmions coexist stably.
Demonstrated effective modulation of the spin spiral state through strain and interaction manipulation.
Highlighted the potential of NiI2 monolayer for two-dimensional multiferroic applications.
Abstract
The spin spiral (SS) state in monolayer (ML) NiI 2 presents a promising avenue for the exploration of two-dimensional multiferroics, but the mechanisms underlying this SS state and its effective modulation...
