Our smart devices are getting increasingly intelligent, but traditional silicon chips used today are reaching physical limits. Future technology will be utilizing quantum spin to process and store data. A promising candidate for future spintronic devices is skyrmions - a stable magnetic whirlpool which can store information with a high density and requires very little energy to do so. This study focused on how the dynamics of skyrmions change with respect to depth in the multilayer material Pt/CoFeB/Ru. This was done through a technique utilizing muons to probe the internal magnetic fields of a material. We discovered that there are depth dependent behavioural changes in the material, and this is crucial to understand for developing skyrmion-based technology.
