Best promising MML systems for hosting skyrmions

Milestone achieved: Decision has been made on the best promising MML systems for hosting skyrmions and one additional information carrier for future prototype devices.

Further explanations: A sample with skyrmions and cocoons or skyrmioniums has been successfully demonstrated. We grew several stacks based on Pt|Co|Al multilayers hosting together skyrmion tubes and cocoons. Based on previous work, we have gradient samples hosting two layers of cocoons as well as skyrmion tubes going through all layers. Since then, we improved the stacks to limit the thickness, favouring motion and nucleation at lower energy.
