1. A magnetic storage device herein referred to as “warped free-layer” comprising: a shape-based dynamic magnetic skyrmion which is a thin film ferromagnetic element shaped in the form of a low-rising bell or dome, either convex or concave, less than 30 nm in diameter, the warped free-layer having a shape including a curved apex and sloping sidewalls extending from the apex, the apex having a radius of curvature smaller than a radius of the diameter of the warped free-layer, the shape of the warped free-layer is configured such that supplemental exchange energy barriers achieve thermal stability through the induction of dynamic vortex magnetization configurations under expressly designed radial components of demagnetization and material-based perpendicular anisotropy fields when a magnetization switch is attempted on it.
