Physical skyrmion diameter \(l_{\text {ph}}\) as a function of the distance of separation h for different tip radius \(R_\text {t}= 5\) nm (black), \(R_\text {t}= 10\) nm (blue), \(R_\text {t}= 15\) nm (red), and \(R_\text {t}= 20\) nm (yellow). Filled symbols with dashed lines correspond to the results of the theoretical method, while open symbols correspond to micromagnetic simulations. Panel a) stands for the atractive mode (tip magnetization pointing in the same direction of the skyrmion core), while b) stands for the repulsive one (tip magnetization pointing opposite to the direction of the skyrmion core).
