摘要：

Magnetic skyrmions are swirl-like spin textures with intriguing topological properties. Topological transitions between skyrmions and other magnetic solitons have been explored to design emerging topological spintronics. In magnets with S-4 and D-2d symmetries, complex magnetic exchange interactions lead to diverse magnetic solitons, including two types of skyrmions and four types of bubbles, which could be applied for multiple-state information processing and storage. However, controlled topological transitions among two types of elliptic skyrmions and four types of bubbles in a controlled manner in strongly confined nanodisks remain elusive. Here, we demonstrate the stabilization and topological transformations of single magnetic solitons in a Fe1.96Ni0.84Pd0.2P nanodisk. Our results show reversible transitions between the two types of skyrmions and four types of bubbles by precisely controlling the in-plane magnetic fields. Further numerical simulations reproduce and agree well with our experiments.
