Abstract
Magnetic topologically non-trivial quasi-particles, such as skyrmions, hopfions, merons, and bimerons that are stabilized by the Dzyaloshinskii–Moriya interaction, have garnered significant interest in recent years. Here, we demonstrate a temperature-driven transition from meron-type textures to out-of-plane stripe domains by continuously tuning the effective anisotropy across the spin reorientation transition. Combined magnetic force microscopy and SQUID magnetometry reveal the temperature-induced evolution of spin structure and anisotropy. Our results establish temperature as a key control parameter for reconfigurable topological states in SyAFM multilayers.
