Transition of Néel‐Type and Bloch‐Néel Hybrid Skyrmion in a Metallic Multilayer Material System

Magnetic skyrmions, which are stable, topologically protected spin structures, have garnered significant interest for their potential in revolutionizing spintronic applications. This study reveals the room‐temperature coexistence of Néel‐type and Bloch‐Néel hybrid skyrmions in [Pt/Co/Cu] multilayers grown by molecular beam epitaxy (MBE). Pulse current is used to switch the skyrmion type and modulate the stability of the skyrmions. The thermal effect on the stability of the skyrmions due to the current pulse is also investigated. The work unveils a broad magnetic phase space, offering unprecedented control over skyrmion states in metallic multilayers with broken inversion symmetry. These findings pave the way for diverse applications in spintronics, including binary data encoding, and provide a novel framework for the manipulation of multi‐type skyrmions.
