Extracting the effective coherence length in Cu. a Red, green and blue data points: radial ZBC profiles of proximity vortex measured in magnetic fields of 5, 55, and 120 mT, respectively. Dashed lines: fits using phenomenological formula suggested in ref. 51; Solid lines: fits using modified de Gennes’ approach developed in ref. 50. Both models fit well the experimental with ξeff = 105–110 nm (see in the text). b Color lines: vortex core profiles (zero-bias conductance) calculated within Usadel framework for different thicknesses of Cu-film in 5 mT field. Dashed lines—best fits using the approximate formula suggested in51 (see in the text). c The ξeff vs δ plot presented in \(\xi _{{\mathrm{eff}}}^2 - 1{\mathrm{/}}\delta\) coordinates
