Hybrid magnetic skyrmions with near-zero Hall angle and electrical switchability in a 2D multiferroic

Magnetic skyrmions hold great promise as information carriers in spintronics, yet their practical implementation is impeded by the skyrmion Hall effect (SkHE). Combining symmetry analysis, first-principles calculations, and atomic spin simulations, we demonstrate hybrid skyrmions in the multiferroic monolayer TcIrGe 2 Se 6 . It hosts a mixed Dzyaloshinskii-Moriya interaction (DMI) containing both parallel and perpendicular components. This unique DMI stabilizes hybrid skyrmions exhibiting a nearly vanishing skyrmion Hall angle, thereby suppressing the SkHE. Benefiting from strong DMI and high Curie temperature (330 K), these hybrid skyrmions maintain stable across a wide temperature and magnetic field range. The intrinsic magnetoelectric coupling enables electrical control of skyrmion chirality and current-driven motion through ferroelectric switching, while strain engineering permits continuous helicity modulation and induces a topological transition to bimerons. Our work establishes TcIrGe 2 Se 6 as a promising platform for hybrid skyrmions and provides a multimodal control scheme, integrating electrical switching for chirality and strain engineering for helicity.
