Ferromagnetic enhancement of Fe3GaTe2/PtTe2 induced by interfacial spin–orbit coupling
Abstract
Spin–orbit coupling (SOC) has been extensively explored for a role in spin manipulation and magnetization control in two-dimensional (2D) nanomagnetic systems. Recent studies highlight the potential of Weyl semimetals characterized by open Fermi arcs, spin momentum locking, and strong SOC effects. In this work, we fabricated a van der Waals heterostructure consisting of the 2D magnet Fe3GaTe2 (FGT) and the Weyl semimetal PtTe2. Anomalous Hall effect measurements reveal that the coercive field of FGT is positively correlated with the thickness of PtTe2. First principles calculations confirm the critical role of SOC in modulating the magnetism of FGT/PtTe2 heterostructures. This study suggests a promising approach for improving magnetic order in 2D ferromagnets and advancing ultra-thin spintronic devices.
